The attached code produces the following output:

construct top
COMMENCE NORMAL COPY
copy construct base
copy construct derived
copy construct top
COMMENCE TEMPLATED COPY
construct base
construct derived
copy construct top
DONE

For the templated copy, I expect the base and derived copy constructors to be
called (as such my application is losing information because these are NOT
being called).
