Trying to Py_DecRef owned reference to builtin "iter" crashes if the reference was alive when runtime was reinitialized. Py_Initialize(); PyObject* builtins = PyEval_GetBuiltins(); PyObject* iter = PyDict_GetItemString(builtins, "iter"); Py_IncRef(iter); Py_Finalize(); // ----- new run starts, iter should still be alive Py_Initialize(); Py_DecRef(iter); Py_Finalize(); // fails inside PyGC_Collect -> validate_list Related on StackOverflow: https://stackoverflow.com/questions/69890182/is-it-safe-to-call-py-decref-on-an-object-created-before-the-last-py-initializ ---------- components: C API messages: 405987 nosy: Victor Milovanov priority: normal severity: normal status: open title: Crash on Py_DecRef'ing builtin object from previous run type: crash versions: Python 3.10, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45758> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
