Claudio Freire added the comment: I cannot be 100% sure, but we have ample evidence suggesting we're experiencing this same crash in production.
We have a big system that mixes Cython and pure-python coroutines, and in one version we started seeing segfaults that strongly hint at this root cause. Adding pure-python indirections (that keep the arguments alive, I'd wager), fixes those segfaults. I cannot share the codebase (and in any case it's too big, and the crash is too difficult to reproduce in isolation, without real traffic), but I'd add my +1 on applying this fix. We're currently testing to try and reproduce the segfaults on 2.7.13, after that I'll try jdemeyer's patch and report the results. ---------- nosy: +Claudio.Freire _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25750> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
