Wow! This is an eye-opener for me! I am quite accustomed to assume two's complement arithmetic with implicit wrap-around for signed integers. After your remark I googled a bit and found several articles about undefined behavior, e.g. John Regehr's "A Guide to Undefined Behavior in C and C++, Part 1". Very instructive.
