Details

(Keywords: assertion, testcase) 

The following testcase asserts on TI revision d78eef12a329 (run with -m -n -a),
tested on 32 bit:

var BUGNUMBER = 96284;
var BUGNUMBER = "410725";
function iteratorToArray(iterator) {
    var result = [];
    for (var i in iterator) BUGNUMBER[result.length];
}
obj = { a: 1, }('["a", "b"]', iteratorToArray(), 'uneval(iteratorToArray(new Iterator(obj,true)))');
Bogus assertion in ImmutableSync, which should be able to manage copies of loop temporaries in the same way as other copies.
