I am working on an application that needs to move objects between different
heaps.  The problem I'm attempting to get a handle on is how to avoid a
stack update of what looks like a pointer to one of the objects moved but is
actually some long or other piece of data that happens to contain the same
values.
It occurs to me that compacting garbage collectors must deal with the same
problem.  Does anyone know of a reasonable solution or a reference to some
piece of literature likely to contain one? I understand that Smalltalk and
Lisp don't have to deal with the problem through the use of tagged
architectures.

Thanks in advance for any help.
