It is the same bug.

I probably should have made mention of "freezing point" rather
than "fully defined."  A tagged type is not considered "fully defined"
in this context until overridings of its primitive subprograms have
occurred.  Hence, if you move the declarations of Initialize,
Adjust, and Finalize up in front of the access type declarations,
it should not end up with multiple definitions.
