Comment (by alexcrichton): The bug seems to be in the `-jump-threading` pass which I suspect is included in the O1 optimizations, yeah, but this technically only arose during O3 when presumably enough inlining had happened to then trigger the bug. I'm not really sure what the best way to avoid this bug would be unfortunately, but I suspect that an `-O1` build should be reproducible (albeit slow). -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/32053#comment:29> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
