Likely due to the clang switch. Not sure about the ync_integration_tests though – some of them also failed on the prior few runs, and the failure message looks identical in all tests I looked at (and identical to the failure message in prior runs).

PrerenderBrowserTest.PrerenderRendererCrash is a new failure. https://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=PrerenderRendererCrash DevToolsReattachAfterCrashTest.TestReattachAfterCrashOnTimeline is also a new failure. https://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=TestReattachAfterCrashOnTimeline

Ah, yeah, likely to due the clang switch. The flakiness dashboard data is just for checking.

After the revert, most sync_integration_tests started passing again but one didn't: https://build.chromium.org/p/chromium.win/builders/Win7%20Tests%20%28dbg%29%281%29/builds/60407 In https://build.chromium.org/p/chromium.win/builders/Win7%20Tests%20%28dbg%29%281%29/builds/60409 with https://chromium-review.googlesource.com/517494 that test stopped failing too. Still not sure if sync_integration_tests is related to the switch, but the two browser tests very likely are.

I can't repro the browser_tests failures locally. Let's try turning them back on: https://chromium-review.googlesource.com/595189

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/aa392a031534cf201903b21b9951f3626f3f535b commit aa392a031534cf201903b21b9951f3626f3f535b Author: Hans Wennborg <hans@chromium.org> Date: Tue Aug 01 06:03:31 2017 Re-enable two browser tests after the win/clang switch These failed during the first win/clang experiment in May (see bug), so were preemptively disabled when we switched to clang. However, they pass for me locally, so it's possible the regression no longer exists.
