New submission from STINNER Victor: The test test_4_daemon_threads() does crash randomly on the buildbot "x86 Windows Server 2003 [SB] 3.x". It may be an old bug which was not seen before because it was hidden by another bug (#19424 which is now fixed).
Charles-François Natali repeated that daemons threads can crash randomly at exit if they are waiting for a blocking call with the GIL released, and still use memory that is being freed by the main thread at exit. http://buildbot.python.org/all/builders/x86%20Windows%20Server%202003%20%5BSB%5D%203.x/builds/2166/steps/test/logs/stdio ====================================================================== FAIL: test_4_daemon_threads (test.test_threading.ThreadJoinOnShutdown) ---------------------------------------------------------------------- Traceback (most recent call last): File "E:\Data\buildslave\cpython\3.x.snakebite-win2k3r2sp2-x86\build\lib\test\test_threading.py", line 773, in test_4_daemon_threads rc, out, err = assert_python_ok('-c', script) File "E:\Data\buildslave\cpython\3.x.snakebite-win2k3r2sp2-x86\build\lib\test\script_helper.py", line 69, in assert_python_ok return _assert_python(True, *args, **env_vars) File "E:\Data\buildslave\cpython\3.x.snakebite-win2k3r2sp2-x86\build\lib\test\script_helper.py", line 55, in _assert_python "stderr follows:\n%s" % (rc, err.decode('ascii', 'ignore'))) AssertionError: Process return code is 3221225477, stderr follows: Related issues: - #19424: _warnings: patch to avoid conversions from/to UTF-8 - #19442: Python crashes when a warning is emitted during shutdown - #19466: Clear state of threads earlier in Python shutdown => my changes from this issue have been reverted ---------- messages: 211830 nosy: haypo, neologix, pitrou, sbt priority: normal severity: normal status: open title: test_4_daemon_threads() fails randomly on "x86 Windows Server 2003 [SB] 3.x" type: crash versions: Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20717> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
