gdb 2002-04-01-cvs segfaults on core file

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:

player.cpp:2241 is:
                        _graphical_attributes->save();
with _graphical_attributes a member of the class player:
        PlayerGraphicalAttributes* _graphical_attributes;

hoping this can help you,
