No traceback :(
Pretty strage as i remember uwsgi sets signal handler for sigsegv.
Is there a way to manually provide traceback?

Further investigation shows segfault happens in

import _socket line in socket.py of python stdlib
(socket.py imported in logging)
Also i enabled gc.debug and it is seems gc is sollecting something before
segfault so think there is a pointer somethere to collected object and
someone is accessing it.

before import _socket

The strange thing also is that import logging.config works ok in
python interactive shell and when run as script.
