New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:
The tp_clear handler of the module object calls a custom clear function if the PyModuleDef.m_clear field is set. This function can set an exception which will be leaked to the garbage collector. An exception in tp_clear is not expected and caused a crash in the garbage collector. In the master branch it will cause just writing a traceback to stderr (see issue33622), but in any case it would be better to handle the failure locally in the module's tp_clear. ---------- components: Interpreter Core messages: 318289 nosy: serhiy.storchaka priority: normal severity: normal status: open title: module can set an exception in tp_clear type: crash versions: Python 2.7, Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33714> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
