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