module a

  interface

    subroutine foo

    end subroutine

  end interface

  external foo  ! { dg-error "Duplicate EXTERNAL attribute" }

end module

module b

  interface

    function sin (x)

      real :: sin, x

    end function

  end interface

  intrinsic sin  ! { dg-error "EXTERNAL attribute conflicts with INTRINSIC attribute" }

end module

! argument checking was not done for external procedures with explicit interface

program c

  interface

    subroutine bar(x)

      real :: x

    end subroutine

  end interface

  call bar()  ! { dg-error "Missing actual argument" }
