Oh wow, that's old! XP is not more supported by Python, but it's no more supported by Microsoft neither. A crash can have various reasons. Usually, it's a buffer overflow or a race condition "somewhere". You should try to collect more information using faulthandler, or maybe using Visual Studio. https://docs.python.org/dev/library/faulthandler.html I suggest you to try to upgrade Windows and Python to more recent versions. Anyway, as Zachary wrote, Python 3.4 is no more supported (only security fixes, nor more bug fixes). ---------- nosy: +haypo _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29090> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
