Was a bug in the doc. Fixed in latest release (3.04):

val make : int -> 'a -> 'a array
[...]
Raise Invalid_argument if n < 0 or n > Sys.max_array_length.

Same behavior as Array.make (ok, maybe it should be in the doc). BTW, it
seems that check is made using same code as Array.make (haven't look at
the code):

# Array.init 0 (fun x -> 0) ;;
- : int array = [||]
# Array.init (-1) (fun x -> 0) ;;
Exception: Invalid_argument "Array.make".
