New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>: I got the following output when run tests in the huntrleaks mode.

It happens after 1.5 hours of running tests. Running the test_multiprocessing_fork test only doesn't expose it. Likely there are already opened related issues, but the assertion failure in PyThreadState_Clear is new, it was added in 3.7. It may help to identify the problem. ---------- messages: 317363 nosy: Mark.Shannon, davin, pitrou, serhiy.storchaka priority: normal severity: normal status: open title: Assertion failure in PyThreadState_Clear type: crash versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33612> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
