I have encountered what appears to be a bug in out_channels created with
Pervasives.open_out_gen:

  bash-2.05a$ ocaml
          Objective Caml version 3.07+2
  
  # let oc = open_out_gen [Open_creat; Open_text] 0o644 "/var/tmp/foo";;
  val oc : out_channel = <abstr>
  # output_string oc "Fubar Baz\n";;
  - : unit = ()
  # close_out oc;;
  Exception: Sys_error "Bad file descriptor".

Well, that's disturbing. Or is there something I don't understand about
the proper usage of open_out_gen (documentation problem?)?

BTW, I'm running OCaml on Debian GNU/Linux 3.0 (Woody), with glibc
2.2.5. I installed OCaml 3.07pl2 from source, with no apparent
compilation errors. I am seeing the same problem on two similarly
configured systems.
