Hello all,

Does someone know why the following code compiles with ocaml 3.11.0 and 
does not with ocaml 3.10.0? I find nothing in the documented ocaml 
changes which could imply such a diff.

=====
let output =
   print_endline ""; (* all is fine without this side effect *)
   (fun fmt -> Format.printf fmt)

let () =
   output "%s" "";
   output ""
=====

Best regards,
Julien Signoles
