A bit of a non-event to me, this is a bug in user code. I don’t see it much differently then freeing a block twice or using an uninitialized pointer. It’s the price of using C.

It’s a footgun for sure though, since the “obvious” comparison function of subtracting arguments is intransitive with integer overflow.
