"This claim that positive signed overflow wraps around is neither correct by the C standard nor consistent with the observed behavior of either GCC or LLVM. This isn’t an acceptable claim to make in a popular C-based textbook published in 2015."

Perhaps someone could explain what I'm missing. It's exactly the behavior that I see using gcc-4.8 and Apple llvm-7.3.
