Summary: 2.2 on linux SEGV sometimes

Initial Comment:
I am using Python 2.2.
The execution with pure python scripts suddenly stops
after several hours or a few days.  With the latest
core I run gdb, it says:

Program terminated with signal 11, Segmentation fault.

and the head of bt is like this:

Can you attach the script, any input data it needs, and
instructions for running it? Otherwise there's no hope in
debugging this.

Also, how long is the stack? Could it be a stack overflow?
