Using ocaml-3.09.3-win-msvc

When I compile the following program as byte code I see a stack overflow (expected).  When using ocamlopt it seems that the program dies and I do not see the expected overflow exception?

>type overflow.ml

let array_1=Array.make 229376 42;;

let _ = Printf.printf "A\n";;

flush stdout;;

let array_2=Array.make 32768 43;;

let _ = Printf.printf "B\n";;

flush stdout;;

let list_1 = Array.to_list(array_1);;

let _ = Printf.printf "C\n";;

flush stdout;;

let list_2 = Array.to_list(array_2);;

let _ = Printf.printf "D\n";;

flush stdout;;

let list_3 = list_1@list_2;;

let _ = Printf.printf "E\n";;

flush stdout;;

Is this a bug?
