But the circumstances seem different.\r\n\r\nIt shows up when built with snapshot, and it also shows up without using the `--always-opt` flag. (this was never true in any observation in bug 113.)\r\n\r\nHere is a log of mips64el builds on the mips buildbot: https://v8.mips.com/bbv8/builders/Target%20-%20MIPS64%20-%20edge?numbuilds=200\r\n\r\nSee build 819, as an example: https://v8.mips.com/bbv8/builders/Target%20-%20MIPS64%20-%20edge/builds/819 -- fails unicodelctest & unicodelctest-no-optimization with the TypeError, and fails another unrelated test, all as flakes.\r\n\r\nNote that build 786 is the build _just before_ commit `e5a082f0 Reland \"Only use FreeSpace objects in the free list\"` was landed. And it fails unicode-case-overoptimization for this same error. The are many others, before and after the commit that fixed the mips32 cases.\r\n\r\nFailures go back to Dec 14, the oldest commit in this log.\r\n\r\nI'll assign to Dusan for now, as Pri 2. If you can think of additional testing or characterization, we can try to find someone to do those tests for us.\r\n"},"comment":{"url":"https://api.github.com/repos/paul99/v8m-rb/issues/comments/115711895","html_url":"https://github.com/paul99/v8m-rb/issues/124#issuecomment-115711895","issue_url":"https://api.github.com/repos/paul99/v8m-rb/issues/124","id":115711895,"user":{"login":"dusmil","id":637736,"avatar_url":"https://avatars.githubusercontent.com/u/637736?v=3","gravatar_id":"","url":"https://api.github.com/users/dusmil","html_url":"https://github.com/dusmil","followers_url":"https://api.github.com/users/dusmil/followers","following_url":"https://api.github.com/users/dusmil/following{/other_user}","gists_url":"https://api.github.com/users/dusmil/gists{/gist_id}","starred_url":"https://api.github.com/users/dusmil/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dusmil/subscriptions","organizations_url":"https://api.github.com/users/dusmil/orgs","repos_url":"https://api.github.com/users/dusmil/repos","events_url":"https://api.github.com/users/dusmil/events{/privacy}","received_events_url":"https://api.github.com/users/dusmil/received_events","type":"User","site_admin":false},"created_at":"2015-06-26T14:43:30Z","updated_at":"2015-06-26T14:43:30Z","body":"Finally fixed in:\r\nhttps://codereview.chromium.org/1220443002/\r\n\r\nThis also fixes dromeo DOM test failure in chromium browser on mips32 (DBUG-1790)\r\n"}}
