It's failing in roughly every other build: http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Linux%2032 http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Linux%2032/builds/20016 http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Linux%2032/builds/20018 http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Linux%2032/builds/20020 Unfortunately I don't have a guess about a probable cause. The first recent build where it appeared to start crashing was: http://build.chromium.org/p/chromium.webkit/builders/Webkit%20Linux%2032/builds/20014 I'm going to suppress this failure in the test expectations for the moment. 655086 1 kbr 2012-06-21 17:54:05 -0700 Committed r120986: <http://trac.webkit.org/changeset/120986> 659376 2 hans 2012-06-28 03:21:44 -0700 I still haven't been able to reproduce this locally, but this is the interesting bit of output from the bot: 16:22:22.845 31571 worker/3 fast/speech/scripted/navigate-away.html passed 16:22:22.892 31571 worker/3 fast/speech/scripted/speechgrammar-basics.html crashed, stack trace: 16:22:22.892 31571 base::debug::StackTrace::StackTrace() [0x82c6874] 16:22:22.893 31571 base::(anonymous namespace)::StackDumpSignalHandler() [0x82b175d] 16:22:22.893 31571 0xb7802400 16:22:22.893 31571 WebCore::EventTarget::fireEventListeners() [0x823e555] 16:22:22.893 31571 WebCore::EventTarget::fireEventListeners() [0x823e711] 16:22:22.893 31571 WebCore::EventTarget::dispatchEvent() [0x823e786] 16:22:22.893 31571 WebCore::SpeechRecognition::didEnd() [0x88e1555] 16:22:22.893 31571 WebKit::SpeechRecognitionClientProxy::didEnd() [0x80f5606] 16:22:22.893 31571 (anonymous namespace)::ClientCallTask::run() [0x8085171] 16:22:22.893 31571 MockWebSpeechRecognizer::StepTask::runIfValid() [0x80854f2] 16:22:22.893 31571 MethodTask<>::run() [0x8085288] 16:22:22.893 31571 invokeTask() [0x808ae79] 16:22:22.893 31571 base::internal::Invoker<>::Run() [0x81c5809] 16:22:22.893 31571 MessageLoop::RunTask() [0x82a48b0] 16:22:22.893 31571 MessageLoop::DeferOrRunPendingTask() [0x82a4f51] 16:22:22.893 31571 MessageLoop::DoWork() [0x82a52b1] 16:22:22.893 31571 base::MessagePumpGlib::HandleDispatch() [0x82c0628] 16:22:22.893 31571 (anonymous namespace)::WorkSourceDispatch() [0x82c0667] 16:22:22.893 31571 0xb75f75e5 16:22:22.893 31571 0xb75fb2d8 16:22:22.893 31571 0xb75fb4b8 16:22:22.893 31571 base::MessagePumpGlib::RunWithDispatcher() [0x82c0af9] 16:22:22.894 31571 base::MessagePumpGlib::Run() [0x82c068e] 16:22:22.894 31571 MessageLoop::RunInternal() [0x82a04de] 16:22:22.894 31571 MessageLoop::Run() [0x82a05f9] 16:22:22.894 31571 webkit_support::RunMessageLoop() [0x81c5faf] 16:22:22.894 31571 TestShell::waitTestFinished() [0x80908d9] 16:22:22.894 31571 TestShell::runFileTest() [0x808ee32] 16:22:22.894 31571 runTest() [0x8067daa] 16:22:22.894 31571 main [0x806843b] 16:22:22.894 31571 0xb6affbd6 16:22:22.894 31571 0x805c311 16:22:22.896 31548 fast/speech/scripted/speechgrammar-basics.html -> unexpected crash I think it's navigate-away.html that's triggering the problem really, but it ends up crashing speechgrammar-basics.html which is run afterwards. Probably something is not right with http://trac.webkit.org/changeset/120913 659479 3 hans 2012-06-28 07:09:07 -0700 I think the patch in bug 90176 should fix this. 660244 4 hans 2012-06-29 00:45:13 -0700 Seems to be fixed by bug 90176.
