92941 2012-08-01 22:07:28 -0700 [Chromium] accessibility/loading-iframe-updates-axtree.html flaky on Win canary 2013-04-08 15:03:54 -0700 1 1 1 Unclassified WebKit Tools / Tests 528+ (Nightly build) Unspecified Unspecified RESOLVED WONTFIX P2 Normal --- 1 pkasting dmazzoni dmazzoni schenney yurys oldest_to_newest 684972 0 pkasting 2012-08-01 22:07:28 -0700 See http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=accessibility%2Floading-iframe-updates-axtree.html . The blame lists here are http://trac.webkit.org/log/?verbose=on&rev=124373&stop_rev=124371 and http://build.chromium.org/f/chromium/perf/dashboard/ui/changelog.html?url=/trunk/src&mode=html&range=149513:149497 . The former doesn't have anything obvious in it. The latter has http://src.chromium.org/viewvc/chrome?view=rev&revision=149510 , but I tried reverting that on the Chromium side for a few hours and the bot didn't stop crashing, so unless it's not rebuilding correctly, that's not the cause either. Dominic, I'm hoping that since you understand the accessibility stuff a bit you might be able to investigate this. 685024 1 dmazzoni 2012-08-01 23:44:23 -0700 I don't see anything in the blamelists either. It made sense to try reverting the accessibility-related change I just landed, but I think it's unlikely to be related; in particular none of that code should be running in DumpRenderTree. I'll try debugging it directly. 685106 2 pkasting 2012-08-02 01:50:56 -0700 (1) Crashing on Win dbg (1) as well (but not Win, dunno why). (2) Flaky -- sometimes this passes. 685752 3 dmazzoni 2012-08-02 13:40:32 -0700 Can repro locally on Win 7, but it's not easy - it's flaky and usually passes for me.
