Summary [WK2] fast/parser/document-open-in-unload.html causes next test to crash

Reported 2012-10-10 15:46:19 PDT
The layout test fast/parser/document-open-in-unload.html will cause the next test to crash when run with WebKit Test Runner. A portion of the backtrace reveals the crash to be inside of the loader: 0 com.apple.WebCore 0x00000001057980dc WebCore::DocumentLoader::isClientRedirect() const + 12 (DocumentLoader.h:124) 1 com.apple.WebCore 0x00000001057918e8 WebCore::FrameLoader::commitProvisionalLoad() + 1784 (FrameLoader.cpp:1750) 2 com.apple.WebCore 0x00000001054c027c WebCore::DocumentLoader::commitIfReady() + 60 (DocumentLoader.cpp:283) 3 com.apple.WebCore 0x00000001054c081c WebCore::DocumentLoader::commitLoad(char const*, int) + 76 (DocumentLoader.cpp:314) 4 com.apple.WebCore 0x00000001054c0cfb WebCore::DocumentLoader::receivedData(char const*, int) + 59 (DocumentLoader.cpp:388) 5 com.apple.WebCore 0x0000000106123b87 WebCore::MainResourceLoader::addData(char const*, int, bool) + 87 (MainResourceLoader.cpp:193) 6 com.apple.WebCore 0x000000010657a1ec WebCore::ResourceLoader::didReceiveData(char const*, int, long long, bool) + 108 (ResourceLoader.cpp:281) 7 com.apple.WebCore 0x0000000106125475 WebCore::MainResourceLoader::didReceiveData(char const*, int, long long, bool) + 1013 (MainResourceLoader.cpp:482) 8 com.apple.WebCore 0x000000010657ab2f WebCore::ResourceLoader::didReceiveData(WebCore::ResourceHandle*, char const*, int, int) + 143 (ResourceLoader.cpp:436) ... It appears that FrameLoader::m_documentLoader becomes null at some point before m_documentLoader->isClientRedirect gets called, causing the crash.

(In reply to comment #0) > The layout test fast/parser/document-open-in-unload.html will cause the next test to crash when run with WebKit Test Runner. Any idea when this started...?
