[Bug fortran/30939] New: Report if dummy array sizes is larger than actual array size

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

NAG f95:
Error: bar.f90, line 6: Array supplied for dummy IN (no. 1) of COPY too small
g95:
Error: Array argument at (1) is smaller than the dummy size
gfortran: No error/warning.

--------------------------
program main
implicit none
character :: digit_arr(10)
call copy(digit_arr)
contains
  subroutine copy(in)
    character, dimension(11) :: in, out
  end subroutine copy
end program main
--------------------------

Note: The other way round is ok, i.e. actual = 1:10, dummy = 1:8
