gdb-fix-crash-when-checking-for-ctor-of-lambda by Thomas VoÃ
Using GDB to debug this test case: http://pastebin.ubuntu.com/1062024/ causes
it to crash in is_ctor_or_dtor.
Attached here patch by Thomas Voà that fixes it.
This is description:
ÂIt turns out that gdb crashes as it tries to determine whether a field of a
lambda is a or ctor/dtor, given the fields name. Apparently, the field's name
is NULL and I added a check for that, bailing out and returning 0 ("no, this is
neither a dtor nor a ctor"). GDB behaves normally when being run on the test
program mentioned before. Patch is attached, generated with quilt.Â
