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'
(3/4294967295) at (1)
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
