[Bug fortran/26041] New: FORTRAN compiler won't compile the valid code

[hjl at lucon dot org]

[hjl@gnu-16 cpu2006-465]$ cat foo.f90
module foo
   public    bar_
   interface bar_
      module procedure bar
   end interface
   public    xxx_
   interface xxx_
      module procedure xxx
   end interface
contains
   subroutine xxx(self,z)
      interface
         function self(z) result(res)
            real(kind=kind(1.0d0)), dimension(:) :: z
            real(kind=kind(1.0d0)) :: res
         end function
      end interface
      call bar_(self)
   end subroutine
   subroutine bar(self)
      interface
         function self(z) result(res)
            real(kind=kind(1.0d0)) :: res
         end function
      end interface
   end subroutine

 In file foo.f90:18

      call bar_(self)
                    1
Error: Generic subroutine 'bar_' at (1) is not an intrinsic subroutine

Intel FORTRAN compiler has no problem. If I remove

            real(kind=kind(1.0d0)), dimension(:) :: z

gfortran can compile it.
