Louie Lu added the comment: Without this segfault, I think you do a wrong operation. In other cases, for example:
>>> issubclass(10, int) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: issubclass() arg 1 must be a class `issubclass` will return TypeError on instance, if you test as `issubclass(Failure, int)` or `issubclass(Failure().__class__, int`, it should get the correct answer. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30570> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
