Ok, so the type is a Storage_Buffer. So is the instance
of the type.

Storage_Buffer : Storage_Buffer;

doesn't get us any closer to solving the problem. ;-)

Sometimes the number of instances is one -- matching the
type.  In cases like these you are still left with the 
task of making them different-- merely for the purpose
making them different.
