--- Comment #2 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
Looking at our -fdump-tree-original, since the derived type contains nothing we
are not building any call to output anything.

>From a practical point of view its a nonsensical case and one could argue to
not bother with this one.

>From a pedantic point of view (or perhaps academic) maybe we should create an
empty call so the user defined procedure gets called.  Very interesting and a
frontend related question.
