Issue 37013: Fatal Python error in socket.if_indextoname() (original) (raw)

Python 3.8.0a4+ (heads/master:ef9d9b6312, May 22 2019, 08:35:25) [GCC 9.0.1 20190402 (experimental) [trunk revision 270074]] on linux Type "help", "copyright", "credits" or "license" for more information.

import socket socket.if_indextoname(2**64 - 1) Fatal Python error: a function returned NULL without setting an error SystemError: returned NULL without setting an error

Current thread 0x00007f29d708d140 (most recent call first): File "", line 1 in Aborted (core dumped)

This is because socket.if_indextoname() does not use PyErr_Occurred() when checking PyLong_AsUnsignedLong() for failure.
