Summary: Random core dumps

Initial Comment:
I have narrowed it down as far as I can by continuing
to make the problem simpler and simpler but where it
still core dumps.

The way this is set up is the following:

pytest2.py and pytest.py are in the same directory.

pytest3.py is in PYTHONPATH where PYTHONPATH is
<abs_path>/BASE:<abs_path>/SUP  (pytest3.py is in BASE).


Run ./pytest2.py several times.
This current problem core dumps on average about 2
times every 5 runs.

I have attached a file that has the Python listings as
well as the gdb traceback.

This is running under Fedora Core 1 with:

Python 2.2.3 (#1, Oct 15 2003, 23:33:35)
[GCC 3.3.1 20030930 (Red Hat Linux 3.3.1-6)] on linux2

Thank you,
Mark

PS  Strangely enough the comments in pytest.py seem to
actually increase the frequency of core dumps.

I have checked out and built Python 2.4b2.  It still core
dumps on these same files but it now takes on average about
8 runs to get 2 cores.

I will attach the 2.4b2 core traceback.

Uh, if that tiny thing cores, I'm very much inclined to
believe there's something flaky in your setup.

I have played some more with the setup.  Now only pytest2.py
and pytest.py need to be present in same directory.

Running pytest2.py will randomly cause core dumps coming
from pytest.py.

If you run pytest.py enough times directly it also will
randomly core.

I have attached pytest.py and pytest2.py.

I have not tried with any other version of Python yet.

Have you tried a more recent Python?

I'm finding decoding your report (attempting to reproduce) a
little challenging.  Could you upload a tarball containing a
shell script driver or something?
