[Python-Dev] stack check on Unix: any suggestions?

Running the program under gdb does no good.  It segfaults and winds up with
a corrupt stack as far as the debugger is concerned.  For some reason bash
won't let me set a core file size != 0 either:

    % ulimit -c
    0
    % ulimit -c unlimited
    % ulimit -c
    0

though I doubt letting the program dump core would be any better
debugging-wise than just running the interpreter under gdb's control.

Kinda weird.
