Created attachment 33834 [details] patch
here the crash bt 53 com.apple.AppKit: NSAccessibilityPostNotification + 28 53 com.apple.WebCore: WebCore::AXObjectCache::notificationPostTimerFired + 94 53 com.apple.WebCore: WebCore::Timer<WebCore::AXObjectCache>::fired + 72 53 com.apple.WebCore: WebCore::ThreadTimers::fireTimers + 78 53 com.apple.WebCore: WebCore::ThreadTimers::sharedTimerFiredInternal + 106 53 com.apple.WebCore: WebCore::ThreadTimers::sharedTimerFired + 22 53 com.apple.WebCore: WebCore::timerFired + 63
i was not able to reproduce this crash, but the backtrace is pretty clear. accessibility objects are being released before the timer can fire and the notification can be posted
so there's no layout test, since i could not repro
