[issue37208] Weird exception behaviour in ProcessPoolExecutor

[Brian Quinlan]

Brian Quinlan <brian at sweetapp.com> added the comment:

That's a super interesting bug! It looks like this issue is that your exception can't be round-tripped using pickle i.e.

>>> class PoolBreaker(Exception):
...     def __init__(self, num):
...         super().__init__()
...         self.num = num
... 
>>> import pickle
>>> pickle.loads(pickle.dumps(PoolBreaker(5)))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: __init__() missing 1 required positional argument: 'num'
