It is impossible to do in general, and I am -1 on any misguided attempts to do so.

I agree, recovering from segfaults caused by buggy third party C modules is a losing proposition, but for a limited number of conditions that can be triggered from python code running on a non-buggy interpreter (hopefully ctypes included, but that would be hard), converting signals into exceptions may be possible. ..

Printing a stack trace and then aborting would be possible and useful though. Even a simple dialog: Python have encountered a segfault, would you like to dump core? y/n in the interactive session will be quite useful.
