           Summary: QtLauncher and jsc ASSERTS when run with valgrind
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kb at inf.u-szeged.hu


Assertion of ./QtLauncher http://www.google.com:
ASSERTION FAILED: !methodCallLinkInfo.cachedStructure
(../../../JavaScriptCore/jit/JITPropertyAccess.cpp:642 static void
JSC::JIT::patchMethodCallProto(JSC::CodeBlock*, JSC::MethodCallLinkInfo&,
JSC::JSFunction*, JSC::Structure*, JSC::JSObject*, JSC::ReturnAddressPtr))
Assertion of ./jsc $WKROOT/SunSpider/tests/sunspider-0.9.1/3d-cube.js
ASSERTION FAILED: !callLinkInfo->isLinked()
(../../../JavaScriptCore/jit/JIT.cpp:600 static void
JSC::JIT::linkCall(JSC::JSFunction*, JSC::CodeBlock*, JSC::CodeBlock*,
JSC::JITCode&, JSC::CallLinkInfo*, int, JSC::JSGlobalData*))

I think these are true positive timing related problems. With valgrind both
QtLauncher and jsc runs 10-20 times slower then normally, that is why I think
about timing.
