This change also caused LayoutTests to exit early due to an assertion failure on Sierra WK1: ASSERTION FAILED: hasHash() /Volumes/Data/slave/sierra-debug/build/WebKitBuild/Debug/usr/local/include/wtf/text/StringImpl.h(520) : unsigned int WTF::StringImpl::existingHash() const 1 0x105d84aad WTFCrash 2 0x10ef67519 WTF::StringImpl::existingHash() const 3 0x10f5cf2d1 WTF::String::existingHash() const 4 0x10f5ce87c WebCore::MediaSessionManagerMac::updateNowPlayingInfo() 5 0x10f5d110d WTF::Function<void ()>::CallableWrapper<std::__1::__bind<void (WebCore::MediaSessionManagerMac::*)(), WebCore::MediaSessionManagerMac*> >::call() 6 0x10ef1fd9b WTF::Function<void ()>::operator()() const 7 0x10f10a5b9 WebCore::GenericTaskQueue<WebCore::Timer>::enqueueTask(WTF::Function<void ()>&&)::'lambda'()::operator()() const 8 0x10f10a379 WTF::Function<void ()>::CallableWrapper<WebCore::GenericTaskQueue<WebCore::Timer>::enqueueTask(WTF::Function<void ()>&&)::'lambda'()>::call() 9 0x10ef1fd9b WTF::Function<void ()>::operator()() const 10 0x1114ccf87 WebCore::TaskDispatcher<WebCore::Timer>::dispatchOneTask() 11 0x1114ccd3f WebCore::TaskDispatcher<WebCore::Timer>::sharedTimerFired() 12 0x1114d0051 WebCore::TaskDispatcher<WebCore::Timer>::sharedTimer()::$_1::operator()() const 13 0x1114d0019 WTF::Function<void ()>::CallableWrapper<WebCore::TaskDispatcher<WebCore::Timer>::sharedTimer()::$_1>::call() 14 0x10ef1fd9b WTF::Function<void ()>::operator()() const 15 0x10ef8e5f9 WebCore::Timer::fired() 16 0x1114fd4b0 WebCore::ThreadTimers::sharedTimerFiredInternal() 17 0x111505391 WebCore::ThreadTimers::setSharedTimer(WebCore::SharedTimer*)::$_7::operator()() const 18 0x111505349 WTF::Function<void ()>::CallableWrapper<WebCore::ThreadTimers::setSharedTimer(WebCore::SharedTimer*)::$_7>::call() 19 0x10ef1fd9b WTF::Function<void ()>::operator()() const 20 0x1114df0d5 WebCore::MainThreadSharedTimer::fired() 21 0x11157ac09 WebCore::timerFired(__CFRunLoopTimer*, void*) 22 0x7fff94103e04 __CFRUNLOOP_IS_CALLING_OUT_TO_A_TIMER_CALLBACK_FUNCTION__ 23 0x7fff94103a93 __CFRunLoopDoTimer 24 0x7fff941035ea __CFRunLoopDoTimers 25 0x7fff940fafc1 __CFRunLoopRun 26 0x7fff940fa544 CFRunLoopRunSpecific 27 0x1040b9387 runTest(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&) 28 0x1040b77dd runTestingServerLoop() 29 0x1040b6c97 dumpRenderTree(int, char const**) 30 0x1040b9dbd DumpRenderTreeMain(int, char const**) 31 0x104134df2 main https://build.webkit.org/builders/Apple%20Sierra%20Debug%20WK1%20%28Tests%29/builds/4438

Plus https://trac.webkit.org/r224121 and https://trac.webkit.org/r224117 to address test problems.

(In reply to Eric Carlson from comment #9) > Plus https://trac.webkit.org/r224121 and https://trac.webkit.org/r224117 to > address test problems. One of the build fixes seems to have caused 2 tests to fail: https://build.webkit.org/results/Apple%20High%20Sierra%20Release%20WK2%20(Tests)/r224121%20(763)/results.html
