Seen while looking at 8.0.1 crash data but happens up to Firefox 9. Mac only issue. https://crash-stats.mozilla.com/report/list?signature=js_ReportOutOfMemory. Comments mention Cityville, Hulu.com, fullscreen slideshow and putting Mac to sleep. https://crash-stats.mozilla.com/report/index/54015373-56ac-4b03-8c8d-33c6c2111127 Frame Module Signature [Expand] Source 0 XUL js_ReportOutOfMemory js/src/jscompartment.h:640 1 XUL JS_SetContextThread js/src/jsapi.cpp:6114 2 XUL nsXPConnect::BeginCycleCollection js/src/xpconnect/src/nsXPConnect.cpp:482 3 XUL nsCycleCollector::BeginCollection xpcom/base/nsCycleCollector.cpp:2728 4 XUL nsCycleCollectorRunner::Run xpcom/base/nsCycleCollector.cpp:3492 5 XUL nsThread::ProcessNextEvent xpcom/threads/nsThread.cpp:631 6 XUL NS_ProcessNextEvent_P obj-firefox/i386/xpcom/build/nsThreadUtils.cpp:245 7 XUL nsThread::ThreadFunc xpcom/threads/nsThread.cpp:272 8 libnspr4.dylib _pt_root nsprpub/pr/src/pthreads/ptthread.c:187 9 libSystem.B.dylib _pthread_start 10 libSystem.B.dylib thread_start

With the exception of a few weird outliers (on FF 3.6.X), the oldest build on which I can find these crashes (on either Windows or OS X) is dated 2011-09-28.
It's #8 top crasher in 8.0.1 on Mac OS X. Here are some correlations per module: js_ReportOutOfMemory|EXC_BAD_ACCESS / KERN_PROTECTION_FAILURE (42 crashes) 93% (39/42) vs. 38% (954/2506) libssl.0.9.7.dylib 98% (41/42) vs. 43% (1074/2506) libcrypto.0.9.7.dylib 100% (42/42) vs. 50% (1265/2506) QuickTime 100% (42/42) vs. 50% (1265/2506) HTMLRendering 100% (42/42) vs. 50% (1265/2506) CarbonSound 100% (42/42) vs. 50% (1265/2506) NavigationServices
fwiw, this crash doesn't exist in this place anymore on trunk, there was temporarily code which accessed cx->thread->data [via JS_THREAD_DATA] without testing cx->thread (which will be null when JS_SetThreadContext fails and needs to report OOM). Today, the crash ends up being in the guy who gets called after JS_SetThreadContext fails and returns. There's another bug for this. If you wanted to make this specific signature go away, code could be added to the 9.0 branch to make it go away, but it'd just move the crash to the next bug report (which isn't an improvement at all). I'd resolve this as "FIXED" this crash was introduced by: http://hg.mozilla.org/mozilla-central/rev/6936f8a3fba7 - Bug 487216 - jorendorff and was removed by this landing: http://hg.mozilla.org/mozilla-central/diff/60f879bef90e/js/src/jscntxt.cpp (you [well, I] crash elsewhere today)
Per comment 4, I close it as fixed.
