It crashes only in the case when the exception is throw from the second most top frame, aka. its caller frame is the top most frame, AND the top most frame is an anonymous function (like an eventHandler).  In this case, m_callFrame->callee() in JSC::debuggerCallFrame::functionName() returns 0x2.  We need to check if this callFrame is top callFrame in [WebScriptCallFrame functionName].
