Incoming string range 0-2**64, but converted to int32 eventually.

func parseAllocateGood4(wanted string) int32 {
    parsed, err := strconv.ParseInt(wanted, 10, 64)
    if err != nil {
        panic(err)
    }
    // GOOD: check for lower and uppper bounds
    if parsed > 0 && parsed <= math.MaxInt32 {
        return int32(parsed)
    }
    return DefaultAllocate
}
