[Bug fortran/30746] New: 50th Anniversary Bug - scoping error

["pault at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Malcolm Cohen's talk to the BCS 50th anniversary of FORTRAN meeting has this
example:

MODULE m
  REAL :: x(3) = (/ 1.5, 2.5, 3.5 /)
CONTAINS
  SUBROUTINE s
    CALL inner
  CONTAINS
    SUBROUTINE inner
      PRINT *,x(7) ! This is not an error!
    END SUBROUTINE
    FUNCTION x(n)
      x = REAL(n)**n
    END FUNCTION
  END SUBROUTINE
END MODULE
  use m
  call s()
end

to which, gfortran incorrectly returns

      PRINT *,x(7) ! This is not an error!
               1
Warning: Array reference at (1) is out of bounds

unless subroutine inner and function x are interchanged.
