Yes, thank you.
But for my understanding: Is there a reason why it is important that zero-sized
objects should sometimes have the same address? I am wondering because I think
zero-sized arrays would make sense to allow in C (it sometimes makes
programming edge cases simpler in numerical code) and at the same time I think
it might be a nice principle to require that all unique objects existing at the
same time should also have a unique address.
