        <p>Bug: rdar://problem/4465598 REGRESSION (TOT): Crash occurs at http://maps.google.com/?output=html ( KJS::Identifier::add(KJS::UString::Rep*)</p> 
        <p>This cause for this bug was that the code to save the window object's property map tried to use
        the deleted property sentinel key as a normal pointer.</p>
        <p>To run this test in Safari:</p>
        <ol>
            <li><a href="resources/go-back.html">Click here to do a back/forward navigation.</a></li>
            <li>You should not crash.</li>
        </ol>
        <p>When the automated version of this test passes, you'll see a PASS message below.
        (The automated version is currently disabled because DumpRenderTree doesn't work
        with the back/forward cache enabled.)</p>
