Bug description

Using Debian unstable, gcc-4.3:

boot/ocamlrun boot/ocamlc -nostdlib -I boot -warn-error A -I utils -I parsing -I typing -I bytecomp -I asmcomp -I driver -I toplevel -c driver/optcompile.ml
File "driver/optcompile.ml", line 97, characters 10-17:
Warning Y: unused variable objfile.
File "driver/optcompile.ml", line 112, characters 16-23:
Unbound value objfile
make: *** [driver/optcompile.cmo] Fehler 2

using CVS checkout of branch release310

cat ocaml/VERSION

3.10.3+dev1 (2008-03-12)

This bug seems to be caused by the last code check-in:
http://camlcvs.inria.fr/cgi-bin/cvsweb/ocaml/driver/optcompile.ml.diff?r1=1.53;r2=1.53.10.1;f=h

Additional information

The new code lines

  let cmxfile = outputprefix ^ ".cmx" in
  let objfile = outputprefix ^ ext_obj in

must be moved before

  try
    if !Clflags.print_types then ignore(

to fix the problem.
