[patch+7.8] Fix crash on optimized-out entry data values Message-Id: <201102071427.55970.pedro@codesourcery.com>
https://sourceware.org/ml/gdb-patches/2014-06/msg00797.html We give preference to printing <optimized out> rather
= than <unavailable>, since if a value had been optimized out
https://bugzilla.redhat.com/show_bug.cgi?id=1111910 at compile time, it can never be collected at run-time.
this can happen for real world -O2 -g executables:
#9 0x0000003b6e0998b2 in wxEntry (argc=@0x7fffffffd86c: 1,
argc@entry=@0x7fffffffd86c: <optimized out>,
^^^^^^^^^^^^^^^
argv=<optimized out>) at src/common/init.cpp:460
GDB did crash in such case.
But the fix was wrong/regressing as shown here: it seems it is just reversed, that 'unavailable' can exist only for
https://bugzilla.redhat.com/show_bug.cgi?id=1117192 !optimized_out and it cannot exist for for optimized_out values.
https://bugzilla.redhat.com/attachment.cgi?id=916298 (at the bottom)
Here is a new fix, also with a new testcase reproducing crash of the wrong fix
above.
No regressions on {x86_64,x86_64-m32,i686}-fedorarawhide-linux-gnu.
> You are right, this patch regresses during gdbserver mode.
It PASSes now even in gdbserver mode.

The problem is that linux_wait_for_event deletes lwps that have exited
(even those not passed in as lwps of interest), while the lwp/thread
list is being walked on with find_inferior. find_inferior can handle
the current iterated inferior being deleted, but not others.
When killing lwps, we don't really care about any of the pending
status handling of linux_wait_for_event. We can just waitpid the lwps
directly, which is also what GDB does (see
linux-nat.c:kill_wait_callback). This way the lwps are not deleted
while we're walking the list. They'll be deleted by linux_mourn
afterwards.
This crash triggers several times when running the testsuite against
GDBserver with the native-gdbserver board (target remote), but as GDB
can't distinguish between GDBserver crashing and "kill" being
sucessful, as in both cases the connection is closed (the 'k' packet
doesn't require a reply), and the inferior is gone, that results in no
FAIL.
The patch adds a generic test that catches the issue with
extended-remote mode (and works fine with native testing too). Here's
how it fails with the native-extended-gdbserver board without the fix:
