It seems there might be a race condition in the run-webkit-tests test harness that is causing this. It's strange that it only affects this single test on Yosemite Debug WK1, though. 1106960 1 ddkilzer 2015-07-05 10:57:04 -0700 See results here: <http://webkit-test-results.appspot.com/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=webgl%2F1.0.2%2Fconformance%2Fmore%2Ffunctions%2FcopyTexImage2DBadArgs.html> 1106963 2 ddkilzer 2015-07-05 11:17:09 -0700 According to the Flakiness Dashboard, this started with: Test run: <https://build.webkit.org/builders/Apple%20Yosemite%20Debug%20WK1%20(Tests)/builds/5818> WebKit trunk r186270: <http://trac.webkit.org/r186270> 1106968 3 ap 2015-07-05 11:27:47 -0700 Looks like this only happens on bot183, every time. 1107037 4 ap 2015-07-06 01:02:19 -0700 In other words, it's probably file system cache corruption, and we should reboot.
