As the multiprocessing doc says (https://docs.python.org/3/library/multiprocessing.html#contexts-and-start-methods): """Note that safely forking a multithreaded process is problematic.""" The reproducer is trivially fixed by adding a call to `multiprocessing.set_start_method("forkserver")` (you can also replace "forkserver" with "spawn") ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45021> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
