[Bug fortran/44135] New: Negative array bounds lead to spurious warning

[thomasr at nikhef dot nl]

The declaration of arrays with negative bounds leads to a warning message,
probably caused by an integer overflow. The program below leads to the message

gprogram.f90:6.19:

   call fill_array(my_arr)
                   1
Warning: Actual argument contains too few elements for dummy argument 'arr'

        program     gprogram
           implicit none

           double precision, dimension(-2:0) :: my_arr

           call fill_array(my_arr)
           print*, my_arr(-2)
           print*, my_arr(-1)
           print*, my_arr( 0)
        contains
           subroutine     fill_array(arr)
              implicit none
              double precision, dimension(-2:0), intent(out) :: arr

              arr(-2) = 1.0d0
              arr(-1) = 3.1d0
              arr( 0) = 9.2d0
           end subroutine fill_array
        end program gprogram
