You are correct. To be more precise, it's caused by GH-16856. The commit introduced PyAttributeErrorObject struct. Since AttributeError and OSError now have an incompatible memory layout, it is no longer possible to create a subclass that has AttributeError and OSError as parent classes. ---------- keywords: +3.10regression nosy: +christian.heimes versions: +Python 3.11 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45464> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
