[issue17669] Segfault caused by weird combination of imports and yield from
New submission from Frank Hamand: I've found a very strange bug in python 3.3 It's taken me around an hour just to narrow it down to a small case where it happens. I cannot for the life of me figure out the exact cause. It seems to have something to do with yield from. I've attached a case which reproduces this. Run python3.3 test.py, it should segfault on linux, stopped responding on windows. Tested with OS: Linux Debian-60-squeeze-32-minimal 2.6.32-5-686-bigmem PY: Python 3.3.1rc1 (default, Mar 30 2013, 21:44:39) OS: Windows 7 64 bit PY: Python 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:55:48) [MSC v.1600 32 bit (Intel)] on win32 NOTES: If you get rid of import logging in generators.py, it only crashes if there's no __pycache__ -- title: Segfault caused by - Segfault caused by weird combination of imports and yield from Added file: http://bugs.python.org/file29744/segfault.zip ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17669 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

R. David Murray added the comment: The crashing version has 'import logging' at the top of generators.py. I did not experience a crash when it was absent even if there was no __pycache__. It also doesn't crash if the import is moved out of the body of first_gen. FAULTHANDLER doesn't fair too well on this one, no real surprise :) Fatal Python error: Segmentation fault Current thread 0xb75856c0: zsh: segmentation fault PYTHONFAULTHANDLER=true ../python test.py -- nosy: +brett.cannon, eric.snow, pitrou, r.david.murray, vinay.sajip versions: +Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17669 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Benjamin Peterson added the comment: This is the patch. I'll have to think about whether there's a self-contained way to test this. -- assignee: - benjamin.peterson keywords: +patch Added file: http://bugs.python.org/file29748/gen_fix.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17669 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
