Description Jessie Berlin 2011-06-23 11:12:25 PDT 
fast/workers/shared-worker-load-error.html		crash log (com.apple.WebCore: WebCore::SharedWorkerScriptLoader::notifyFinished() + 197)
fast/workers/worker-context-multi-port.html		crash log (com.apple.JavaScriptCore: JSC::HandleHeap::visitWeakHandles(JSC::HeapRootVisitor&) + 120)
http/tests/workers/shared-worker-redirect.html		crash log (com.apple.WebCore: WebCore::DocumentThreadableLoader::willSendRequest(WebCore::SubresourceLoader*, WebCore::ResourceRequest&, WebCore::ResourceResponse const&) + 85)
http/tests/xhtmlmp/xhtml.xhtmlmp		crash log (com.apple.JavaScriptCore: JSC::HandleHeap::visitWeakHandles(JSC::HeapRootVisitor&) + 120)

These crashes started happening somewhere in (89499, 89505]:

http://build.webkit.org/builders/SnowLeopard%20Intel%20Release%20%28WebKit2%20Tests%29/builds/12823
http://build.webkit.org/builders/SnowLeopard%20Intel%20Release%20%28WebKit2%20Tests%29/builds/12824
http://build.webkit.org/results/SnowLeopard%20Intel%20Release%20(WebKit2%20Tests)/r89505%20(12824)/results.html

They are not appearing on the Windows WK2 bots. Only one of the 4 is skipped on Windows (all http/tests/workers).

I see 3 potential culprits:

http://trac.webkit.org/changeset/89503
http://trac.webkit.org/changeset/89504

and possibly

http://trac.webkit.org/changeset/89505
Comment 1 Ryosuke Niwa 2011-06-23 11:29:43 PDT 
Definitely not http://trac.webkit.org/changeset/89505.
Comment 2 Darin Fisher (:fishd, Google) 2011-06-23 14:05:34 PDT 
And http://trac.webkit.org/changeset/89504 could not have had anything to do with this since the only WebCore change was to add a function that the PLATFORM(MAC) port doesn't call.
