           Summary: Date object prototype functions improperly access
                    internalValue (Crash)
           Product: WebKit
           Version: 412+
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: JavaScript
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: maksim at kde.org


DateProtoFuncImp::callAsFunction will call internalValue->toNumber on most 
inputs, w/o checking the type. This can a) crash (see below) b) seems wrong 
since I do not see it in the spec that most methods of Date.prototype should 
be generic. 
 
Sample testcase: 
Math.__proto__.crash = Date.prototype.getDate; 
Math.crash(); 
 
(spotted when trying to push internalValue further down into hierarchy)
