Description Christian Holler (:decoder) 2011-04-27 15:11:17 PDT
The following testcase asserts on TI revision 09cce9915b80 (run with -m -n -a),
tested on 64 bit:

const HAVE_TM = 'tracemonkey' in this;
const HOTLOOP = HAVE_TM ? tracemonkey : 8;
with(evalcx(''))(function eval() {}, this.__defineGetter__("x", Function));
var i = 0;
var o;

I'm not sure if it's valid due to the evalcx call in there.

When invoking a constructor on a dummy frame we would query the current frame's script to check whether to create a unique type object for the result.  Needed a guard to check the frame actually has a script.
