I don't really know where this belongs, but it is at least for me not an expected behaviour. It is weird for me at all. Please take a look if this is an intended behaviour and why it is like that.

Tested with py3.7.3, py3.8.0b1
A process in the process pool was terminated abruptly while the future was running or pending.

Tested with py 3.6.8:
Exception in thread Thread-1:
Traceback (most recent call last):
  File "C:\Python36\lib\", line 916, in _bootstrap_inner
  File "C:\Python36\lib\", line 864, in run
    self._target(*self._args, **self._kwargs)
  File "C:\Python36\lib\concurrent\futures\", line 272, in _queue_management_worker
    result_item = reader.recv()
  File "C:\Python36\lib\multiprocessing\", line 251, in recv
    return _ForkingPickler.loads(buf.getbuffer())
TypeError: __init__() missing 1 required positional argument: 'num'

I expect that the PoolBreaker exception would work too.

Code to test:
