The following testcase asserts on TI revision fd1abc43d698 (run with -m -n -a),
tested on 64 bit:


function throwsRangeError(t) {
    try {
        t: for (t[t++] in object) {
            t++
            break t;
        }
        date(t)
    } catch (err) {}
}
throwsRangeError(Infinity);
Oversight, we would allow register allocations at join points to assign FP registers to entries which weren't being tracked by the analysis (only possible in scripts with try or switch blocks), and which we don't require to match analysis information at join points.
