ceval.c no such file or dir and SIGSEGV

[Nancy]

Hi,

I'm running 2.4 Python. I have an extension program that calls C funcs.
Actually I have a C prog that calls python that calls C. In a python to
C function call I get a SIGSEGV and this stack trace. I have print
statements that show it made it into the C extension function, and
within there its crashing with this trace. gdb also puts up a popup
that says Python/ceval.c
No such file or directory.
Thanks.

 Program received signal SIGSEGV, Segmentation fault.
