Sorry, it's been crazy busy and there were other fixes I really needed to get upstream. If it really is superfluous, the compiler will optimize it away. I have been bitten more times than I can count with fuzz testers and C's _fine_ signed vs. unsigned integer semantics. So I prefer to be careful here. If we can really be sure it's safe, we can always remove the extra comparison in a separate patch, since that's unrelated to the real bug we're trying to fix. - Ted
