The example below should be valid but is currently rejected:

$ cat procpointer.f90
  IMPLICIT NONE
  TYPE :: a
    PROCEDURE(proc), POINTER, NOPASS :: p
  END TYPE
  ABSTRACT INTERFACE
    SUBROUTINE proc
    END SUBROUTINE
  END INTERFACE
  TYPE(a), PARAMETER :: aa = a(aproc)     ! <--- 
CONTAINS
  SUBROUTINE aproc
  END SUBROUTINE
END

$ gfortran-svn -Wall -W -fimplicit-none procpointer.f90

  TYPE(a), PARAMETER :: aa = a(aproc)     ! <--- 
                                    1
Error: Symbol 'aproc' at (1) has no IMPLICIT type
