To answer seriously, the memory has been marked available on the heap but it still exists and is not cleared. You still have a pointer to it although it's invalid. If that block of memory was allocated to something else later in the program, who knows what would happen but probably nothing good. If an invalid pointer is going to be in scope for a while, it's a good idea to null it out and get an immediate crash if you happen to use it again.
You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.
