Infinite for loop in JavaScript.

270 Thread_0f0f
...
270 KJS::SourceElementsNode::execute(KJS::ExecState*)
264 KJS::ForNode::execute(KJS::ExecState*)

Downgrading to P2 because the general issue of being able to cancel run-away JavaScript is a separate P1 in Radar, so the unique issue here is just a compatibility bug, not a hang.

Actually, it doesn't actually freeze - it just takes several minutes to successfully open.

The site sends some special ultra-slow code to Safari; spoofing the UA makes it work fast, and without any immediately visible issues (even with shipping Safari).

menu.js:
scriptNo=(nua.indexOf('Safari')>-1)?7:(nua.indexOf('Gecko')>-1)?2:((document.layers)?3:((nua.indexOf('Opera')>-1)?4:((nua.indexOf('Mac')>-1)?5:1)));
Comment 4 Alexey Proskuryakov 2007-10-30 06:05:25 PDT 
I can no longer reproduce this (and the site has a new design).
