Feature or enhancement

Proposal:

The faulthandler module allows registering a SIGSEGV handler to print a Python stacktrace if the program encounters a segfault. However, if developing C/C++ extension modules that may not be particularly useful on its own, and you also want the the C stacktrace.
The suggested API would be a kwarg to faulthandler.enable().

Implementation could use https://github.com/timmaxw/cfaulthandler as a starting point, timmaxw/cfaulthandler@561dbdd in particular.

The availability/usability of the feature would likely depend on platform and/or compile flags.

Has this already been discussed elsewhere?
