The problem can be reduced to this:
---
function f() {
for(var i=0; i<3; i++) {
var x = -i / 100;
assertEq(x * -100, i);
}
}
f();
---
It does x = -i and seems to ignore the whole division.

The problem was in the jsop_neg(), if it had an int32 operand and known-double result then the result would be marked as double but still have an int32 bit representation.
