Description John Resig 2013-10-24 09:57:54 PDT 
Calling the code `Object.freeze(window)` will cause the browser to redirect to `./undefined`. Not sure if this should be a JS bug or a DOM bug so I'm filing in JavaScriptCore for now.

This appears to happen in Safari 6.1, Safari 7, Blackberry 10.2, and WebKit Nightly.

Test case:

Will end up redirecting to:
