bpo-39091: Fix segfault when Exception constructor returns non-exception for gen.throw #17658

coolreader18 · 2019-12-19T05:08:20Z

I added a type check in _PyErr_CreateException as @serhiy-storchaka suggested.

I'm not sure if I should replace the check in do_raise in ceval.c with a call to _PyErr_CreateException somehow, as it's effectively the same functionality?

do_raise has a complex code. Unless it contains similar bug I suggest to left refactoring to other issue.
