           Summary: Using built-in type Constructor objects as keys fails
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: awiner at gmail.com

Run the following page.  In FF 2.0 and IE 7.0, you see
"n b s d a m".  In Safari, you just see "m"!   Somehow,
all of these constructors are considered the same key
within an Object - this despite String == Object being
false.

Repros on both MacOS 419.3 and Windows 522.13.1.

<html>
<head>
<script>
var typeMap = new Object();
typeMap[Number] = "n";
typeMap[Boolean] = "b";
typeMap[String] = "s";
typeMap[Date] = "d";
typeMap[Array] = "a";
typeMap[Object] = "m";

var str = "";
for (var i in typeMap)
{
  str += typeMap[i] + " ";
}
</script>
</head>
<body>
<div id ='someId' onclick="testHtml()">Hi</div>
</body>
</html>
