Set a watchpoint on obj (this step may be unneccessary)\r\n4. Reverse continue.\r\n\r\nNote that I ran the above steps on Linux Mint in VMWare Fusion on OS X.\r\n\r\nExpected results:\r\nThe watchpoint eventually triggers.\r\n\r\nActual results:\r\nrr eventually displays the following message:\r\n\r\nrr: /home/ejpbruel/Projects/rr/src/ReplayTimeline.cc:213: void rr::ReplayTimeline::mark_after_singlestep(const rr::ReplayTimeline::Mark&, const rr::ReplayResult&): Assertion `i + 1 < mark_vector.size() && mark_vector[i + 1] == m.ptr' failed.\r\nRemote connection closed\r\n\r\nAfter this, I can no longer debug the program.\r\n"},"comment":{"url":"https://api.github.com/repos/mozilla/rr/issues/comments/251501335","html_url":"https://github.com/mozilla/rr/issues/1833#issuecomment-251501335","issue_url":"https://api.github.com/repos/mozilla/rr/issues/1833","id":251501335,"user":{"login":"rocallahan","id":296135,"avatar_url":"https://avatars.githubusercontent.com/u/296135?v=3","gravatar_id":"","url":"https://api.github.com/users/rocallahan","html_url":"https://github.com/rocallahan","followers_url":"https://api.github.com/users/rocallahan/followers","following_url":"https://api.github.com/users/rocallahan/following{/other_user}","gists_url":"https://api.github.com/users/rocallahan/gists{/gist_id}","starred_url":"https://api.github.com/users/rocallahan/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/rocallahan/subscriptions","organizations_url":"https://api.github.com/users/rocallahan/orgs","repos_url":"https://api.github.com/users/rocallahan/repos","events_url":"https://api.github.com/users/rocallahan/events{/privacy}","received_events_url":"https://api.github.com/users/rocallahan/received_events","type":"User","site_admin":false},"created_at":"2016-10-04T20:21:15Z","updated_at":"2016-10-04T20:21:15Z","body":"We fixed a leak since 4.3.0 that caused rr to crash with OOM during some reverse-continues. If you watch rr's memory usage and see it growing a lot, that's probably what you're hitting.\r\n\r\nWhether that's it or not, 4.3.0 is quite old now so it's probably not worth spending any more time investigating unless you can reproduce on master.\r\n\r\nThanks!!!"}}
