The first question, as always, is why you're using access types, and why 
you care how the compiler represents them. As an apparent beginner in 
Ada, you should not need access types, unless you're doing an assignment 
on dynamic data structures.

String_Ptr isn't a pointer; it's an access type. As pointed out in 
another thread, access values are not necessarily pointers, and that's 
why they're not called pointers. In this case, the extra space is 
probably connected to the bounds information needed for the array.

Probably the difference between pointers in simple languages and access 
values in high-level languages. In C/++, a pointer is an int is an 
address. In Ada, they're 3 different things.
