> For ints we've got UBSan, but unsigned ints are defined on wrap. There's no unsigned type that's UB on overflow - certainly might be nice to have them to clarify the difference between a think you want to do weird bitfiddling with and expect all the overflow, etc, and a thing that's meant to do maths and where sanitizers could diagnose overflow, etc.

-fsanitize=signed-integer-overflow ?
