--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
>   In fact, N is an 32-bit INTEGER in the range [-2147483648 ; 2147483647]

This is true even for arrays of 64-bit INTEGER:

integer(8) :: i(4)
print *, i
end

compiled with -finit-integer=2147483648 gives at run time

          -2147483648          -2147483648          -2147483648         
-2147483648

at least since gcc 4.8.5.
