The likely culprit is the set_next() loop. Perhaps it is never safe to use set_next() because any lookup can callback to __eq__ which can mutate the set. Since set_isdisjoint() method isn't a mutating method, that is the easiest place to start investigating. Try disabling the exact set fast path to see if the issue persists. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46615> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
