My point was that this isn't possible, because the addressable memory, whiles possible humongous, is always finite, because the sizeof pointers is constant. So

My point was that this isn't possible, because the addressable memory, whiles possible humongous, is always finite, because the sizeof pointers is constant. So at some point `malloc` must return the same address, even if you had theoretically infinite memory available, there is no way to address that in C.
