> The crash (the one we're experiencing) still happens with 2.7.13. But at this point it's not clear whether it's a Python bug or a Cython bug, as jdemeyer's patch doesn't fix it. We're having a hard time getting accurate backtraces to actually debug this thing, as it only happens on production servers.

I suggest you to try faulthandler to try to get a traceback ;-)
