I'm also getting segfaults in PyMarshal_ReadLastObjectFromFile in Python 2.6.2 (on Ubuntu Jaunty).  It's very sporadic, I've been reproducing it by running a minimal script 100,000 times, and getting a few core dumps.  There are several Ubuntu bugreports in various packages that use Python:

https://bugs.launchpad.net/ubuntu/+source/apport/+bug/393022
https://bugs.launchpad.net/ubuntu/+source/gnome-python/+bug/432546
https://bugs.launchpad.net/ubuntu/+source/streamtuner/+bug/336331

I've attached a zip file with my test scripts and some gdb backtraces.  I am happy to spend time on this bug, although I only have a rudimentary knowledge of C, so I'd mainly be useful for testing.

The computer I'm having trouble on is a Dell PowerEdge T410, with a Xeon E5502, and it had another sporadic segfault problem in a should-be-reliable program, ImageMagick.  Switching to GraphicsMagick fixed that one, somehow.  If it's a hardware-specific bug, Python is the only program that's tickling it right now...
