New submission from Maries Ionel Cristian: Running the file couple of times will make the interpreter fail with: libgcc_s.so.1 must be installed for pthread_cancel to work
>From what I've seen it is triggered from PyThread_delete_key (tries to load >libgcc_s.so at that time). How does it happen? The main thread will close fd 4 (because fh object is getting dereferenced to 0) exactly at the same time libpthread will try to open and read libgcc_s.so with the same descriptor (4) It's fairly obvious that the file handling in bug.py is a bug, but the interpreter should not crash like that ! This doesn't happen on python2.7. Also, python2.7 appears to be linked with libgcc_s.so.1 directly while the 3.x does not (I've tried 3.2 from ubuntu repos, and built 3.3 and 3.4 myself on ubuntu 12.04.2) - at least that's what ldd indicates. ---------- components: Build, Extension Modules files: bug.py messages: 195253 nosy: ionel.mc priority: normal severity: normal status: open title: libgcc_s.so.1 must be installed for pthread_cancel to work type: crash versions: Python 3.2, Python 3.3, Python 3.4 Added file: http://bugs.python.org/file31301/bug.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18748> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
