Yes, the derived type could contain all sorts of bizarrenesses that would
prevent an adjusted stride from working.  I agree that the third option is
awkward and pessimising; in addition, I just do not have the competence to
implement it.

This is why I went for the first option.  I have modified the test to check to
see if ->ts.derived is the same for the expression and the symbol, rather than
the type.  This allows derived_type = derived_type_function (args) to work. I
was about to try the same for the rvalue.
