|
;;[gdb/cli] Don't assert on empty string for core-file
|
|
;;(Tom de Vries)
|
|
|
|
With current gdb we run into:
|
|
...
|
|
$ gdb -batch '' ''
|
|
: No such file or directory.
|
|
pathstuff.cc:132: internal-error: \
|
|
gdb::unique_xmalloc_ptr<char> gdb_abspath(const char*): \
|
|
Assertion `path != NULL && path[0] != '\0'' failed.
|
|
...
|
|
|
|
Fix this by skipping the call to gdb_abspath in core_target_open in the
|
|
empty-string case, such that we have instead:
|
|
...
|
|
$ gdb -batch '' ''
|
|
: No such file or directory.
|
|
: No such file or directory.
|
|
$
|
|
...
|
|
|
|
Tested on x86_64-linux.
