[New-bugs-announce] [issue28342] OSX 10.12 crash in urllib.request getproxies_macosx_sysconf and proxy_bypass_macosx_sysconf

[Alexander Mohr]

New submission from Alexander Mohr:

I have a unittest which spawns several processes repeatedly.  One of these subprocesses uses botocore, which itself uses the above two methods through the calls proxy_bypass and getproxies.  It seems after re-spawning the methods a few times the titled calls eventually repeatedly cause python to crash on 10.12.  I have a core file if that would help, zip'd it's ~242MB.

I've attached a file that shows the lldb callstack and python callstack.
