For the fun, could you try this one ? It does not allocate the
exception in the loop but outside.

  -------------------------------------------------
 exception Break
 
 let _ =
   let ary = [|1;2;3;4;5;6;7;8;9;10;11;12|] in
   let exn = Break in
     for i = 1 to 1_000_000_000 do
       try
         for j = 1 to 10 do
           if ary.(j) = 5 then
             raise exn
         done
       with Break -> ()
     done 
 ------------------------------------------------------
