Dereferencing of this in this case is effectively an implementation detail. I'm not saying that the this pointer is not defined by the standard, because it is, but from a semantically abstracted standpoint what is the purpose of allowing the use of objects that have been destroyed, just because there is a corner case in which in practice it will be "safe"? None. So it's not. No object exists, so you may not call a function on it.
