The above isn't true if we only compare if we only look if the pointer  
address we assigned previously hasn't changed (and this is what we did  
before).

Nevertheless, I really dislike the prior way of checking for changes  
and would rather see that pointers that are used for dynamic memory  
are initialized to NULL and free'd unconditionally before allocating  
memory to them. This makes it much easier to prevent leaking memory.

Best regards, Arjen
