Preprocessor error for bitmatch after semicolon

[GoogleCodeExporter]

What steps will reproduce the problem?
1. make

What is the expected output? What do you see instead?

expected compile without errors; got the following output:

make
ocamlfind ocamlc test1.ml -package bitstring.syntax -syntax bitstring
File "test1.ml", line 8, characters 11-12:
Error: Unbound value v
make: [all] Error 2 (ignored)
ocamlfind ocamlc test2.ml -package bitstring.syntax -syntax bitstring
File "test2.ml", line 10, characters 6-14:
Parse error: "end" expected after [class_structure] (in [class_expr])
File "test2.ml", line 1, characters 0-1:
Error: Preprocessor error

What version of the product are you using? On what operating system?
bitstring 2.0.2, ocaml 3.11.2, gentoo linux 32 bit

Please provide any additional information below.

It looks like for some reason bitmatch expression does not like simicolon 
before it. I attached two samples - one for with regular function, other with 
class.

Put parentheses around the bitmatch statement:

let test v =
  f ();
  (bitmatch v with
   | {_} -> ())

I believe this is mentioned in the documentation.
