In Ada, a pointer is not an integer and has no 'Image attribute. A
pointer is not an address either. Of course, for debugging you can
indulge your self to constructs that would be thrown at for long term
maintenance. So...
1) Use Unchecked_Conversion to convert it to an appropriate integer type
2) use package Address_To_Access conversion to convert your pointer to
an address, then System.Storage_Elements.To_Integer to convert the
address to Integer_Address, which is an integer type.
