Debugging with multiprocess causes exception in Pycharm

Hello,

I am seeing an exception when debugging code that uses the multiprocess library -- it looks like an exception will get thrown in Pycharm when the child process terminates.The script will run fine when running from the command line.

I have put together a small sample the reproduces the error that I see -- this is on Pycharm 2018-3.4, Python 3.7. I am also using a virtual environment.

When debugging under Pycharm, I see the following error:

pydev debugger: process 6684 is connecting

Here is my sample code:

from multiprocessing import Process

def worker():
    """worker function"""
    print('Worker')
    return


class TestProcess(Process):

    def __init__(self):
        super(TestProcess, self).__init__()

    def run(self):
       print('Worker')
       return

if __name__ == '__main__':
    jobs = []
    for i in range(5):
        p = TestProcess()
        jobs.append(p)

    for p in jobs:
        p.start()
        p.join()
