Could someone please tell me whether the error message below is a compiler bug or a requirement of the Fortran 2008 standard?
type object

                                  1
Error: As extending type 'periodic' at (1) has a coarray component, parent type 'object' shall also have one

That's Fortran 2008's:

C432 (R425) If EXTENDS appears and the type being defined has a coarray ultimate component, its parent type shall have a coarray ultimate component.
