Created attachment 184429 [details] crash report Since about 10 days, the WebKit nightlies crash on me seemingly randomly. I can't tell the exact revision at which it started (Is the revision somewhere in the crash report?) It seems it's not connected to a specific website or user action, I was just reading on a site, without doing anything at the time of the crash. Thus I can't reproduce the crash, but it was still happening with r140374 Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 com.apple.WebCore 0x0000000109c4aa1c WebCore::CachedResource::makePurgeable(bool) + 204 1 com.apple.WebCore 0x0000000109c42872 WebCore::CachedCSSStyleSheet::destroyDecodedData() + 114 2 com.apple.WebCore 0x000000010a8a00ff WebCore::ThreadTimers::sharedTimerFiredInternal() + 159 3 com.apple.WebCore 0x000000010a728c93 WebCore::timerFired(__CFRunLoopTimer*, void*) + 51 4 com.apple.CoreFoundation 0x00007fff8c67bda4 __CFRUNLOOP_IS_CALLING_OUT_TO_A_TIMER_CALLBACK_FUNCTION__ + 20 5 com.apple.CoreFoundation 0x00007fff8c67b8bd __CFRunLoopDoTimer + 557 6 com.apple.CoreFoundation 0x00007fff8c661099 __CFRunLoopRun + 1513 7 com.apple.CoreFoundation 0x00007fff8c6606b2 CFRunLoopRunSpecific + 290 8 com.apple.HIToolbox 0x00007fff87cb10a4 RunCurrentEventLoopInMode + 209 9 com.apple.HIToolbox 0x00007fff87cb0e42 ReceiveNextEventCommon + 356 10 com.apple.HIToolbox 0x00007fff87cb0cd3 BlockUntilNextEventMatchingListInMode + 62 11 com.apple.AppKit 0x00007fff89c6c613 _DPSNextEvent + 685
