Possible soureces of this error

[Chris Saunders-4]

I'm getting this error:

VGCC(6): Creation instruction uses call to improper feature.
MPFR_REF.next_above (complex_general_1_project)

Here is the function this error is being reported for:

 next_above: like Current
   -- Equivalent to `next_toward' with `other' set to +infinity.
  do
   create Result.make (Current)
   {MPFR_FUNCTIONS}.mpfr_nextabove (Result.item)
  end

Now the class this is from does have a `make' procedure and does declare it
as a creation procedure.  Can anyone think of a reason why I should get this
error from the compiler?

Found the solution to this but I think the compiler error message was
misleading me.  I was creating an expanded class inheriting from another and
so far had just used `default_create' as the creation procedure in the
expanded class.  The compiler error directed me to the class I was
inheriting from as the source of the error but the problem was actually in
the expanded class.  I wonder if the compiler could be aware of this kind of
problem?

Usually when validating inherited code, the compiler gives the location in the
inherited class which causes the error for the descendant class.
