Previous and subsequent builds under the same conditions work fine and start 2 workers as expected. This is with LLVM 3.7.1.\r\n\r\nIt also seems that the tests completely break down for some reason, probably related.\r\n\r\nI don't dare copying the messy output here, but see the end of this log:\r\nhttps://copr-be.cloud.fedoraproject.org/results/nalimilan/julia-nightlies/fedora-23-x86_64/00156219-julia/build.log.gz"},"comment":{"url":"https://api.github.com/repos/JuliaLang/julia/issues/comments/176231864","html_url":"https://github.com/JuliaLang/julia/issues/14828#issuecomment-176231864","issue_url":"https://api.github.com/repos/JuliaLang/julia/issues/14828","id":176231864,"user":{"login":"tkelman","id":5934628,"avatar_url":"https://avatars.githubusercontent.com/u/5934628?v=3","gravatar_id":"","url":"https://api.github.com/users/tkelman","html_url":"https://github.com/tkelman","followers_url":"https://api.github.com/users/tkelman/followers","following_url":"https://api.github.com/users/tkelman/following{/other_user}","gists_url":"https://api.github.com/users/tkelman/gists{/gist_id}","starred_url":"https://api.github.com/users/tkelman/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/tkelman/subscriptions","organizations_url":"https://api.github.com/users/tkelman/orgs","repos_url":"https://api.github.com/users/tkelman/repos","events_url":"https://api.github.com/users/tkelman/events{/privacy}","received_events_url":"https://api.github.com/users/tkelman/received_events","type":"User","site_admin":false},"created_at":"2016-01-28T15:19:05Z","updated_at":"2016-01-28T15:19:05Z","body":"The reason for the number of workers is due to all the failures, waiting to report all of them until the end, Something is fishy and intermittent with pointer conversions in many of the tests, possibly due to https://github.com/JuliaLang/julia/commit/639621859863609c5f3abbc2ed75c675695b3693 or some other recent commit. I've seen this a handful of times on travis and appveyor and locally too, but only since yesterday."}}
