Perhaps I'm just naive and/or have forgotten too much C, not that I knew that much, but I'm a bit perplexed as to why this is UB.
It seems like something that should trigger a "we should specify this" reaction when adding these operators, and there is at least one reasonable way to define it which is fairly trivial and easily implementable.
