I encountered a segfault of gdb 2002-04-01-cvs (Debian Sarge package) when
running it on a (huge) core file generated by a C++ program (compiled with
g++ 3.2).
Here is a trace of gdb running gdb:
(gael@pc137082, 16) ~/mkigen/run $ gdb gdb

Core was generated by `/home/gael/mkigen/apps/login/login /home/gael/mkigen/orb.cfg'.
Program terminated with signal 11, Segmentation fault.

player.cpp:2241 is:
_graphical_attributes->save();
with _graphical_attributes a member of the class player:
PlayerGraphicalAttributes* _graphical_attributes;
hoping this can help you,
