The attached patch (wrap_threadstate.diff) is enough to stop the crash. It's a slightly dirty proof-of-concept, but equally could be the basis for a solution. The main functional issue is that there's still a race on the Py_BLOCK_THREADS side: it's possible that the "is threadstate still valid" check can pass, but the interpreter is finalised while the daemon thread is trying to reacquire the GIL in PyEval_RestoreThread. (The Py_UNBLOCK_THREADS side is non-racy as the GIL is held while the ts and wrapper updates are done). ---------- Added file: https://bugs.python.org/file48732/wrap_threadstate.diff _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33608> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
