            Bug ID: 105038
           Summary: Improve error message for recursive type
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vivekrao4 at yahoo dot com
  Target Milestone: ---

For the code

module m
implicit none
type :: t
   integer :: i
   type(t) :: x
end type t
end module m

gfortran says

recursive_type.f90:5:15:

    5 |    type(t) :: x
      |               1
Error: Component at (1) must have the POINTER attribute

but the code compiles if x has either the POINTER or ALLOCATABLE attribute, and
the error message should reflect this.
