Subject: [PATCH] Destroy {GDBM,NDBM,ODBM,SDBM}_File objects only from original
thread context
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch fixes a crash when destroing a hash tied to a *_File
database after spawning a thread:
use Fcntl;
use SDBM_File;
use threads;
tie(my %dbtest, 'SDBM_File', "test.db", O_RDWR|O_CREAT, 0666);
threads->new(sub {})->join;
This crashed or paniced depending on how perl was configured.
Closes RT#61912.

+
+ExtUtils::MM::Utils - ExtUtils::MM methods without dependency on ExtUtils::MakeMaker
+
+=head1 SYNOPSIS
+
+ require ExtUtils::MM::Utils;
+ MM->maybe_command($file);
+
+=head1 DESCRIPTION
+
+This is a collection of L<ExtUtils::MM> subroutines that are used by many
+other modules but that do not need full-featured L<ExtUtils::MakeMaker>. The
+issue with L<ExtUtils::MakeMaker> is it pulls in Perl header files and that is
+an overkill for small subroutines.
+
+An example is the L<IPC::Cmd> that caused installing GCC just because of
+three-line I<maybe_command()> from L<ExtUtils::MM_Unix>.
+
+The intentions is to use L<ExtUtils::MM::Utils> instead of
+L<ExtUtils::MakeMaker> for these trivial methods. You can still call them via
+L<MM> class name.
+
+=head1 METHODS
+
+=over 4
+
+=item maybe_command
+
+Returns true, if the argument is likely to be a command.
+
+=cut
+
+if (!exists $INC{'ExtUtils/MM.pm'}) {
+ *MM::maybe_command = *ExtUtils::MM::maybe_command = \&maybe_command;
+}
+
+sub maybe_command {
+ my($self,$file) = @_;
+ return $file if -x $file && ! -d $file;
+ return;
+}
+
+1;
+
+=back
+
+=head1 BUGS
+
+These methods are copied from L<ExtUtils::MM_Unix>. Other operating systems
+are not supported yet. The reason is this
+L<a hack for Linux
+distributions|https://bugzilla.redhat.com/show_bug.cgi?id=1129443>.

clean up gv_fetchmethod_pvn_flags: introduce name_end
nend is used for too many things, this replaces various
uses of nend with name_end, which is constant.
this is a first step to fixing [perl #129267], which shouldnt

Petr Pisar: Ported to 5.24.0:
commit 7332835e5da7b7a793ef814a84e53003be1d0138
Author: David Mitchell <davem@iabyn.com>
Date: Mon Nov 28 08:03:49 2016 +0000
crash on explicit return from s///e
RT #130188
In
sub f {
my $x = 'a';
$x =~ s/./return;/e;
}
the 'return' triggers popping any contexts above the subroutine context:
in this case, a CXt_SUBST context. In this case, Perl_dounwind() calls
cx_popblock() for the bottom-most popped context, to restore any saved
vars. However, CXt_SUBST is the one context type which *doesn't* use
'struct block' as part of its context struct union, so you can't
cx_popblock() a CXt_SUBST context.
This commit makes it skip the cx_popblock() in this case.
Bug was introduced by me with v5.23.7-235-gfc6e609.

splice needs to take into account that arrays can hold NULLs and

regcomp.c: fix perl #129950 - fix firstchar bitmap under utf8 with prefix optimisation
The trie code contains a number of sub optimisations, one of which
extracts common prefixes from alternations, and another which isa
bitmap of the possible matching first chars.
The bitmap needs to contain the possible first octets of the string
which the trie can match, and for codepoints which might have a different
first octet under utf8 or non-utf8 need to register BOTH codepoints.
So for instance in the pattern (?:a|a\x{E4}) we should restructure this
as a(|\x{E4), and the bitmap for the trie should contain both \x{E4} AND
\x{C3} as \x{C3} is the first byte of \x{EF} expressed as utf8.

[rt #129336] #!perl -i u erroneously interpreted as -u
Perl_moreswitches processes a single switch, and returns a pointer
to the start of the next switch. It can return either
the a pointer to the next flag itself:
#!perl -n -p
^ Can point here
Or, to the space before the next "arg":
#!perl -n -p
^ Can point here
(Where the next call to Perl_moreswitches will consume " -".)
In the case of -i[extension], the pointer is by default pointing at
the space after the end of the argument. The current code tries to
do the former, by unconditionally advancing the pointer, and then
advancing it again if it is on a '-'. But that is incorrect:
#!perl -i p
^ Will point here, but that isn't a flag
I could fix this by removing the unconditional s++, and having it
increment by 2 if *(s+1)=='-', but this work isn't actually
necessary - it's better to just leave it pointing at the space after
the argument.

commit 71ca73e5fa9639ac33e9f2e74cd0c32288a5040d
Author: David Mitchell <davem@iabyn.com>

split was leaving PL_sv_undef in unused ary slots
This:
@a = split(/-/,"-");
$a[1] = undef;
$a[0] = 0;
was giving
Modification of a read-only value attempted at foo line 3.
This is because:
1) unused slots in AvARRAY between AvFILL and AvMAX should always be
null; av_clear(), av_extend() etc do this; while av_store(), if storing
to a slot N somewhere between AvFILL and AvMAX, doesn't bother to clear
between (AvFILL+1)..(N-1) on the assumption that everyone else plays
nicely.
2) pp_split() when splitting directly to an array, sometimes over-splits
and has to null out the excess elements;
3) Since perl 5.19.4, unused AV slots are now marked with NULL rather than
&PL_sv_undef;
4) pp_split was still using &PL_sv_undef;
The fault was with (4), and is easily fixed.

commit e452bf1c9e9f30813b1f289188a6e8b0894575ba

buffer overrun with format and 'use bytes'
RT #130703
In the scope of 'use bytes', appending a string to a format where the
format is utf8 and the string is non-utf8 but contains lots of chars
with ords >= 128, the buffer could be overrun. This is due to all the
\x80-type chars going from being stored as 1 bytes to 2 bytes, without
growing PL_formtarget accordingly.
This commit contains a minimal fix; the next commit will more generally
tidy up the grow code in pp_formline.

don't call Perl_fbm_instr() with negative length
RT #131575
re_intuit_start() could calculate a maximum end position less than the
current start position. This used to get rejected by fbm_intr(), until
v5.23.3-110-g147f21b, which made fbm_intr() faster and removed unnecessary
checks.
This commits fixes re_intuit_start(), and adds an assert to fbm_intr().

Date: Fri Jan 27 10:18:51 2017 +0100
fix RT #130561 - recursion and optimising away impossible quantifiers are not friends
Instead of optimising away impossible quantifiers like (foo){1,0} treat them
as unquantified, and guard them with an OPFAIL. Thus /(foo){1,0}/ is treated
the same as /(*FAIL)(foo)/ this is important in patterns like /(foo){1,0}|(?1)/
where the (?1) needs to be able to recurse into the (foo) even though the
(foo){1,0} can never match. It also resolves various issues (SEGVs) with patterns
like /((?1)){1,0}/.
This patch would have been easier if S_reginsert() documented that it is
the callers responsibility to properly set up the NEXT_OFF() of the inserted
node (if the node has a NEXT_OFF())

commit 4b9c7caeaecf4e9df0be3a2e296644f763f775d6

fix pad/scope issue in re_evals
RT #129881 heap-buffer-overflow Perl_pad_sv
In some circumstances involving a pattern which has embedded code blocks
from more than one source, e.g.
my $r = qr{(?{1;}){2}X};
"" =~ /$r|(?{1;})/;
the wrong PL_comppad could be active while doing a LEAVE_SCOPE() or on
exit from the pattern.
This was mainly due to the big context stack changes in 5.24.0 - in
particular, since POP_MULTICALL() now does CX_LEAVE_SCOPE(cx) *before*
restoring PL_comppad, the (correct) unwinding of any SAVECOMPPAD's was
being followed by C<PL_comppad = cx->blk_sub.prevcomppad>, which wasn't
necessarily a sensible value.
To fix this, record the value of PL_savestack_ix at entry to S_regmatch(),
and set the cx->blk_oldsaveix of the MULTICALL to this value when pushed.
On exit from S_regmatch, we either POP_MULTICALL which will do a
LEAVE_SCOPE(cx->blk_oldsaveix), or in the absense of any EVAL, do the
explicit but equivalent LEAVE_SCOPE(orig_savestack_ix).
Note that this is a change in behaviour to S_regmatch() - formerly it
wouldn't necessarily clear the savestack completely back the point of
entry - that would get left to do by its caller, S_regtry(), or indirectly
by Perl_regexec_flags(). This shouldn't make any practical difference, but
is tidier and less likely to introduce bugs later.

+ * don't want to clear the save stack on exit from the

+ * Also for efficiency we don't want to keep pushing and

fix special-case recreation of *::
If *:: is called for then as a special case it is looked up as
$::{"main::"}. If $::{"main::"} has been deleted, then that hash entry
is recreated. But formerly it was only recreated as an undef scalar,
which broke things relying on glob lookup returning a glob. Now in
that special case the recreated hash entry is initialised as a glob,
and populated with the customary recursive reference to the main stash.
Fixes [perl #129869].

(perl #129125) copy form data if it might be freed
If the format SV also appeared as an argument, and the FF_CHOP
operator modified that argument, the magic and hence the compiled
format would be freed, and the next iteration of the processing
the compiled format would read freed memory.
Unlike my original patch this copies the formsv too, since
that is also stored in the magic, and is needed for presenting
literal text from the format.

[perl #129342] ensure range-start is set after error in tr///
A parse error due to invalid octal or hex escape in the range of a
transliteration must still ensure some kind of start and end values
are captured, since we don't stop on the first such error. Failure
to do so can cause invalid reads after "Here we have parsed a range".

[perl #131085] Crash with sub-in-stash
$ perl -e '$::{"A"} = sub {}; \&{"A"}'
Segmentation fault (core dumped)
The code that vivifies a typeglob out of a code ref assumed that the
CV had a name hek, which is always the case when perl itself puts the
code ref there (via sub A{}), but is not necessarily the case if
someone is insinuating other stuff into the stash.

[perl #131211] fixup File::Glob degenerate matching
The old code would go quadratic with recursion and backtracking
when doing patterns like "a*a*a*a*a*a*a*x" on a file like
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa".
This patch changes the code to not recurse, and to not backtrack,
as per this article from Russ Cox: https://research.swtch.com/glob
It also adds a micro-optimisation for M_ONE and M_SET under the new code.
Thanks to Avar and Russ Cox for helping with this patch, along with
Jilles Tjoelker and the rest of the FreeBSD community.

[perl #131263] clear the UTF8 flag on a glob if it isn't UTF8
Previously sv_2pv_flags() would set the UTF8 flag on a glob if it
had a UTF8 name, but wouldn't clear tha flag if it didn't.
This meant a name change, eg. if assigned another glob, from a UTF8
name to a non-UTF8 name would leave the flag set.

commit 3c157b3cf0631c69ffa5aa2d55b9199bf93b22a9
Author: Zefram <zefram@fysh.org>
Date: Mon Jan 23 02:25:50 2017 +0000
permit goto at top level of multicalled sub
A multicalled sub is reckoned to be a pseudo block, out of which it is
not permissible to goto. However, the test for a pseudo block was being
applied too early, preventing not just escape from a multicalled sub but
also a goto at the top level within the sub. This is a bug similar, but
not identical, to [perl #113938]. Now the test is deferred, permitting
goto at the sub's top level but still forbidding goto out of it.

commit d729f63cc94318c248eab95844cfbed5298a7ecd
Author: David Mitchell <davem@iabyn.com>
Date: Tue May 9 14:29:11 2017 +0100
sprintf(): add memory wrap tests
In various places Perl_sv_vcatpvfn_flags() does croak_memory_wrap()
(including a couple added by the previous commit to fix RT #131260),
but there don't appear to be any tests for them.
So this commit adds some tests.

This broke some time between 1.29 (perl 5.18) and 1.3301 (perl 5.20):
$ perl5.20.1 -e 'package Foo { use constant ISA => 42; Bar::f() } package Bar { use Carp; sub f { carp "tun syn" } }'
Not a GLOB reference at /usr/local/lib/perl5/5.20.1/Carp.pm line 560.
and still persisted in bleadperl (Carp 1.43) until this commit.
The code that goes poking through the symbol table needs to take into
account that not all stash elements are globs.

Subject: [PATCH] fix tainting of s/// with overloaded replacement
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The substitution code was trying to track the taintedness of the
replacement string itself, but it didn't account for the replacement
being an untainted object with overloading that returns a tainted
stringification. It looked at the taintedness of the object value, not
realising that taint could arise during the string concatenation per se.
Change the taint checks to look at the actual TAINT_get flag after string
concatenation. This may falsely ascribe to the replacement taint that
actually came from somewhere else, but the end result is the same anyway:
there's no visible behaviour that distinguishes taint specifically from
the replacement. Also remove a related taint check that seems to be
not needed at all. Fixes [perl #115266].

Subject: [PATCH] (perl #132245) don't try to process a char range with no
preceding char
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
A range like \N{}-0 eventually results in compilation failing, but
before that, get_and_check_backslash_N_name() attempts to treat
the memory before the empty output of \N{} as a character.

Subject: [PATCH] Fix stack with do {my sub l; 1}
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
A block in perl usually compiles to a leave op with an enter inside
it, followed by the statements:
leave
enter
nextstate
... expr ...
nextstate
... expr ...
If a block contains only one statement, and that statement is suffic-
iently innocuous, then the enter/leave pair to create the scope at run
time get skipped, and instead we have a simple scope op which is not
even executed:
scope
ex-nextstate
... expr ...
The nextstate in this case also gets nulled.
In the case of do { my sub l; 1 } we were getting a variation of the
latter, that looked like this:
scope
introcv
clonecv
nextstate
... expr ...
The problem here is that nextstate resets the stack, even though a new
scope has not been pushed, so we end up with all existing stack items
from the *outer* scope getting clobbered.
One can have fun with this and erase everything pushed on to the stack
so far in a given statement:
$ ./perl -le 'print join "-", 1..10, do {my sub l; ","}, 11..20'
11,12,13,14,15,16,17,18,19,20
Here I replaced the first argument to join() from within the do{}
block, after having cleared the stack.
Why was the op tree was getting muddled up like this? The my sub
declaration does not immediately add any ops to the op tree; those ops
get added when the current scope finishing compiling, since those ops
must be inserted at the beginning of the block.
I have not fully looked into the order that things happen, and why the
nextstate op does not get nulled; but it did not matter, because of
the simple fix: Treat lexical sub declarations as not innocuous by
setting the HINT_BLOCK_SCOPE flag when a lexical sub is declared.
Thus, we end up with an enter/leave pair, which creates a
proper scope.

Subject: [PATCH] set $! when statting a closed filehandle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When a stat fails because it's on a closed or otherwise invalid
filehandle, $! was often not being set, depending on the operation
and the nature of the invalidity. Consistently set it to EBADF.
Fixes [perl #108288].

Subject: [PATCH] Remove ext/GDBM_File/t/fatal.t
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
gdbm-1.15 defaults to a memory-mapped I/O and does not report any I/O
errors on store and close operations. Thus ext/GDBM_File/t/fatal.t
test that expects these fatal error reports fails. Because there is
no other way to provoke a fatal error in gdbm-1.15 this patch
removes the test. Future gdbm version promisses reporting a regular
error on closing a database.

Subject: [PATCH] perform system() arg processing before fork
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
A lot of things can happen when stringifying an argument list: side
effects, warnings, exceptions. In the case of system(), these effects
should happen in the context of the parent process. The stringification
can also depend on which process it happens in, as in the case of
$$, and in that case it should also happen in the parent process.
Therefore reduce the argument scalars to strings first thing in pp_system.
Fixes [perl #121105].

commit 2814f4b3549f665a6f9203ac9e890ae1e415e0dc
Author: Hugo van der Sanden <hv@crypt.org>
Date: Tue Oct 4 14:40:11 2016 +0100
[perl #129350] anchored/floating substrings must be utf8 if target is
If the target is utf8 and either the anchored or floating substrings
are not, we need to create utf8 copies to check against. The state
of the two substrings may not be the same, but we were only testing
whichever we planned to check first.

The following SEGVed:
sub P::f{}
undef *P::;
*P::f =sub{};
due to the code which generates the "Subroutine STASH::NAME redefined"
warning assuming that the GV always has a stash. Make it so that if it
hasn't, the message changes to "Subroutine NAME redefined" rather than
just crashing.

MIME-Version: 1.0

RT #128238
%: = 0 would cause an assertion failure in Perl_gv_check(), since when
it searched a stash for substashes, it assumed anything ending in ':' was
a substash, whereas substashes end in '::'. So check for a double colon
before recursing.

This is a follow-up to e7acdfe976f. Even if the name of the stash
entry ends with ::, it may not itself contain a real stash (though
this only happens with code that assigns directly to stash entries,
which has undefined behaviour according to perlmod), so skip hashes
that are not stashes.

This will be useful for cases where the results don't readily fall into
fresh_perl_is and fresh_perl_like, such as when a bunch of massaging of
the results is needed before it is convenient to test them.
fresh_perl_like() could be used, but in the case of failure there could
be lines and lines of noise output.

Subject: [PATCH 4/5] fix #129267: rework gv_fetchmethod_pvn_flags separator
parsing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
With previous code we could overrun the end of the name when
the last char in the string was a colon. This reworks the code
so it is more clear what is going on, and so it more similar
to other code that also parses out package separaters in gv.c.
This is a rework of the reverted patches:
243ca72 rename "nend" name_cursor in Perl_gv_fetchmethod_pvn_flags

The & and &. operators were not appending a null byte to the string

(The internal function that they use is the same. I used &. in the
test just because its intent is clearer.)

Subject: [PATCH] Fix Storable segfaults.
Fix a null pointed dereference segfault in storable when the
retrieve_code logic was unable to read the string that contained
the code.
Also fix several locations where retrieve_other was called with a
null context pointer. This also resulted in a null pointer
dereference.

Subject: [PATCH] only mess with NEXT_OFF() when we are in PASS2

Content-Transfer-Encoding: 8bit
In 31fc93954d1f379c7a49889d91436ce99818e1f6 I added code that would modify
NEXT_OFF() when we were not in PASS2, when we should not do so. Strangly this
did not segfault when I tested, but this fix is required.

Subject: [PATCH] [perl #129061] CURLYX nodes can be studied more than once
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
study_chunk() for CURLYX is used to set flags on the linked WHILEM
node to say it is the whilem_c'th of whilem_seen. However it assumes
each CURLYX can be studied only once, which is not the case - there
are various cases such as GOSUB which call study_chunk() recursively
on already-visited parts of the program.
Storing the wrong index can cause the super-linear cache handling in
regmatch() to read/write the byte after the end of poscache.
Also reported in [perl #129281].

Subject: [PATCH] fix do dir returning no $!
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
do()ing a directory was returning false/empty string in $!, which isn't
an error, yet documentation says $! should have the error code in it.
Fix this by returning EISDIR for dirs, and EINVAL for block devices.
[perl #125774]
Remove "errno = 0" and comment added in b2da7ead68, since now there is no
scenario where errno is uninitialized, since the dir and block device
failure branches now set errno, where previously they didn't.

Subject: [PATCH] (perl #131746) avoid undefined behaviour in Copy() etc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
These functions depend on C library functions which have undefined
behaviour when passed NULL pointers, even when passed a zero 'n' value.
Some compilers use this information, ie. assume the pointers are
non-NULL when optimizing any following code, so we do need to
prevent such unguarded calls.
My initial thought was to add conditionals to each macro to skip the
call to the library function when n is zero, but this adds a cost to
every use of these macros, even when the n value is always true.
So instead I added asserts() which will give us a much more visible
indicator of such broken code and revealed the pp_caller and Glob.xs
issues also patched here.

Subject: [PATCH] [perl #131221] improve duplication of :via handles
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Previously duplication (as with open ... ">&...") would fail
unless the user supplied a GETARG, which wasn't documented, and
resulted in an attempt to free and unreferened scalar if supplied.
Cloning on thread creation was simply broken.
We now handle GETARG correctly, and provide a useful default if it
returns nothing.
Cloning on thread creation now duplicates the appropriate parts of the
parent thread's handle.

Perl_my_atof2() calls GROK_NUMERIC_RADIX() to detect and skip past

checking what it points at, so skipping the terminating NUL if the
decimal point is immediately before the NUL.

Subject: [PATCH] avoid 'the address of ... will always evaluate as ...' warns
in mem macros
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In f14cf363205 we added asserts to our memory macros (Copy(), Zero() etc)
to ensure that the target is non-null. These asserts throw warnings like
perl.c: In function Perl_eval_sv:
perl.c:2976:264: warning: the address of myop will always evaluate
as true [-Waddress]
Zero(&myop, 1, UNOP);
which is annoying. This patch changes how these asserts are coded so
we avoid the warning. Thanks to Zefram for the fix.

Subject: [PATCH] Reenable numeric first argument of system() on VMS.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This was broken in 64def2aeaeb63f92dadc6dfa334, and fixed for Win32
only in 8fe3452cc6ac7af8c08. But VMS also uses a numeric first
argument to system() as a flag indicating spawn without waiting for
completion.

Subject: [PATCH] preserve numericness of system() args on Win32
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On Windows there's a nasty variation in the meaning of arguments
to Perl's system(), in which a numeric first argument isn't used as
part of the command to run, but instead selects between two different
operations to perform with the command (whether to wait for the command
to complete or not). Therefore the reduction of argument scalars to
their operative values in the parent process, which was added in commit
64def2aeaeb63f92dadc6dfa33486c1d7b311963, needs to preserve numericness
of arguments on Windows. Fixes [perl #132633].

Subject: [PATCH] hints/linux: Add -lphtread to lddlflags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Passing -z defs to linker flags causes perl to fail to build if threads are
enabled:
gcc -shared -Wl,-z,relro -Wl,-z,defs -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -L/usr/local/lib -fstack-protector-strong Bzip2.o -o ../../lib/auto/Compress/Raw/Bzip2/Bzip2.so \
-L/usr/lib64 -lbz2 "-L../.." -lperl \
Bzip2.o: In function `deRef':
/builddir/build/BUILD/perl-5.26.1/cpan/Compress-Raw-Bzip2/Bzip2.xs:256: undefined reference to `pthread_getspecific'
The reason is Bzip2.xs calls dTHX macro included from thread.h via perl.h that
expands to pthread_getspecific() function call that is defined in pthread
library. But the pthread library is not explicitly linked to Bzip.so (see the
gcc command). This is exactly what -z defs linker flag enforces.
Underlinking ELFs can be dangerous because in case of versioned
symbols it can cause run-time binding to an improper version symbol or
even to an symbold from different library.
This patch fixes hints for Linux by adding -lpthreads to lddlflags. It
also adds -shared there because Configure.sh adds it only hints return
lddlflags empty.
