New submission from Thomas Caswell <tcasw...@gmail.com>: https://github.com/python/cpython/commit/e1becf46b4e3ba6d7d32ebf4bbd3e0804766a423 causes pyqt5 to segfault an accessing an attribute
To reproduce this: pip install pyqt5 pip install sip python -c "import PyQt5.QtCore; PyQt5.QtCore.Qt.Key_Control" # this segfaults Setting up faulthandler gives: jupiter@23:54 ➤ python -X faulthandler -c "import PyQt5.QtCore; PyQt5.QtCore.Qt.Key_Control" Fatal Python error: Segmentation fault Current thread 0x00007f52111cd740 (most recent call first): <no Python frame> Segmentation fault (core dumped) It is likely that this should also be reported to riverbank as a pyqt/sip bug, but I'm starting here. I apologize for not having a simpler reproducing case. jupiter@00:01 ➤ git bisect log git bisect start # good: [2d8757758d0d75882fef0fe0e3c74c4756b3e81e] bpo-40286: Remove C implementation of Random.randbytes() (GH-19797) git bisect good 2d8757758d0d75882fef0fe0e3c74c4756b3e81e # bad: [d10091aa171250c67a5079abfe26b8b3964ea39a] bpo-40502: Initialize n->n_col_offset (GH-19988) git bisect bad d10091aa171250c67a5079abfe26b8b3964ea39a # good: [c3f001461d5794c81cf5f70e08ae5435fe935ceb] bpo-40491: Fix typo in syntax error for numeric literals (GH-19893) git bisect good c3f001461d5794c81cf5f70e08ae5435fe935ceb # good: [c21c51235aa8061da6b0593d6f857f42fd92fd8b] bpo-40355: Improve error messages in ast.literal_eval with malformed Dict nodes (GH-19868) git bisect good c21c51235aa8061da6b0593d6f857f42fd92fd8b # good: [c1c7d8ead9eb214a6149a43e31a3213c52448877] bpo-40397: Refactor typing._GenericAlias (GH-19719) git bisect good c1c7d8ead9eb214a6149a43e31a3213c52448877 # bad: [c068b53a0ca6ebf740d98e422569d2f705e54f93] bpo-38787: Update structures.rst docs (PEP 573) (GH-19980) git bisect bad c068b53a0ca6ebf740d98e422569d2f705e54f93 # good: [4638c6429575bd6de26b12b2af5df74d6568b553] bpo-40334: Error message for invalid default args in function call (GH-19973) git bisect good 4638c6429575bd6de26b12b2af5df74d6568b553 # bad: [8963a7f1f84a05412178b56629508b660d38861b] bpo-40545: Export _PyErr_GetTopmostException() function (GH-19978) git bisect bad 8963a7f1f84a05412178b56629508b660d38861b # bad: [e1becf46b4e3ba6d7d32ebf4bbd3e0804766a423] bpo-38787: C API for module state access from extension methods (PEP 573) (GH-19936) git bisect bad e1becf46b4e3ba6d7d32ebf4bbd3e0804766a423 # first bad commit: [e1becf46b4e3ba6d7d32ebf4bbd3e0804766a423] bpo-38787: C API for module state access from extension methods (PEP 573) (GH-19936) ---------- components: C API messages: 368499 nosy: tcaswell priority: normal severity: normal status: open title: segfault causing regression from PEP 573 implementation versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40574> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
