[Caml-list] Re: Size limitation on input_value

[Yaron Minsky <yminsky@gmail.com>]

So, I've investigated this a little further, and it's a definite
regression.  Here's the function I used:

# let run ~save ~load n =
  let ar = Array.init n (fun i -> (i,i+1,i+2,i+3)) in
  if save then begin
    let f = open_out_bin "foo.val" in
    output_value f ar;
    close_out f
  end;
  if load then begin
    let f = open_in_bin "foo.val" in
    ignore (input_value f);
    close_in f 
  end;;
val run : save:bool -> load:bool -> int -> unit = <fun>

If I run this on 3.07, i get this:

# run ~save:true ~load:true 1000000;;
- : unit = ()

On 3.08, I get this:

# run ~save:true ~load:true 1000000;;
Out of memory during evaluation.
# run ~save:true ~load:false 1000000;;
Out of memory during evaluation.
# run ~save:false ~load:false 1000000;;
- : unit = ()
# 

So, the exception comes when saving, not when generating the data.

Is this a known bug?  Are there any patches available?
