STINNER Victor <vstin...@python.org> added the comment:
_Py_DumpTracebackThreads() should not use Py_DECREF(). It's a bug. It must only *read* memory, not *modify* memory since it's called from a signal handler. It's a regression in dump_traceback(). Python 3.9 and 3.10 use: frame = PyThreadState_GetFrame(tstate); ... Py_DECREF(frame); The main branch (future 3.11) uses: frame = tstate->frame; Without Py_DECREF(): it's a borrowed reference. It was changed by commit ae0a2b756255629140efcbe57fc2e714f0267aa3. Python 3.9 and 3.10 should be fixed to use a borrowed reference. ---------- nosy: +vstinner _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44449> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
