PyEval_RestoreThread(tstate) was called with a freed PyThreadState: tstate->interp = 0xdbdbdbdbdbdbdbdb for example. I recently fixed PyEval_RestoreThread() in bpo-39877 to exit properly daemon theads without dereferencing tstate which points to freed memory. To reproduce the bug, it helped me to add a sleep at Python exit. Fixed value (ex: 1 second) or better: random sleep (between 1 ms and 1 sec). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37127> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
