Description Vicki Pfau 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.

Any idea when this started...?
