This is a bug in the Windows DumpRenderTree implementation, not a problem with WebKit itself. The following layout tests fail due to this error: http/tests/globalhistory/history-delegate-basic-302-redirect.html http/tests/globalhistory/history-delegate-basic-title.html http/tests/globalhistory/history-delegate-pushstate.html http/tests/globalhistory/history-delegate-replacestate.html
