[New-bugs-announce] [issue30385] Segfault on OSX with 3.6.1

Wed May 17 08:40:55 EDT 2017
New submission from Gunnar Aastrand Grimnes:
This script, using requests and multiprocessing, will segfault on MacOS 16.4.0 with python 3.6.1. In 3.6.0 it runs fine.
The program is reduced from a much larger program, some weird things need to be present to trigger the crash. For instance the unused tornado imports on the top.
