Jan Kratochvil c75bd3a239 Fix crash on Python frame filters with unreadable arg ... https://bugzilla.redhat.com/show_bug.cgi?id=1126177 ERROR: AddressSanitizer: SEGV on unknown address 0x000000000050 (pc 0x000000992bef sp 0x7ffff9039530 bp 0x7ffff9039540 T0) #0 0x992bee in value_type .../gdb/value.c:925 #1 0x87c951 in py_print_single_arg python/py-framefilter.c:445 #2 0x87cfae in enumerate_args python/py-framefilter.c:596 #3 0x87e0b0 in py_print_args python/py-framefilter.c:968 It crashes because frame_arg::val is documented it may contain NULL (frame_arg::error is then non-NULL) but the code does not handle it. Another bug is that py_print_single_arg() calls goto out of its TRY_CATCH which messes up GDB cleanup chain crashing GDB later. It is probably 7.7 regression (I have not verified it) due to the introduction of Python frame filters. gdb/ChangeLog PR python/17355 * python/py-framefilter.c (py_print_single_arg): Handle NULL FA->VAL. Fix goto out of TRY_CATCH. gdb/testsuite/ChangeLog PR python/17355 * gdb.python/amd64-py-framefilter-invalidarg.S: New file. * gdb.python/py-framefilter-invalidarg-gdb.py.in: New file. * gdb.python/py-framefilter-invalidarg.exp: New file. * gdb.python/py-framefilter-invalidarg.py: New file.		2014-09-07 14:09:59 +02:00
