Ok, I found the problem. The problem is that the reproduced does not correctly work the reference count of base_class because when construction get tuple of bases: PyObject *bases = PyTuple_New(1); result = PyTuple_SetItem(bases, 0, base_class); if (result) return -1; PyObject *subclass = PyType_FromModuleAndSpec(m, &subclass_spec, bases); "PyTuple_SetItem" steals a reference to base_class but "PyModule_AddObject" also does the same, and the refcount is incorrect. If you add a Py_INCREF before, the crash disappears. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40217> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
