pickle and cPickle cause really often segfaults when dumping or loading user defined classes. It happens with python 2.7.3 on 64bits architecture, with any protocol (0,1,2).
I attach an example of class afflicted by this problem.
Solutions anyone?

Please provide a self-contained explain, we can reproduce.

If you are pickling large objects, you're likely hitting issue #11872. We fixed most 64-bit issues in Python 3, so upgrading might be solution if possible.

Since the particular bug you are hitting cannot be reproduced with your test case, I am closing this issue. Feel free to reopen if you come up with a reproducible test case.
