[New-bugs-announce] [issue24927] multiprocessing.Pool hangs forever on segfault

[Jonas Obrist]

New submission from Jonas Obrist:

When using multiprocessing.Pool, if the function run in the pool segfaults, the program will simply hang forever. However when using multiprocessing.Process directly, it runs fine, setting the exitcode to -11 as expected.

I would expect the Pool to behave similar to Process, or at the very least an exception to be raised instead of just silently hanging forever.

I was able to reproduce this issue both on Linux (Ubuntu 15.04) and Mac OS X.
