Subject: [Caml-list] ocamlyacc bug?

Is the following an ocamlyacc bug?

When making application with using ocamlyacc + ocamllex,
you can make main function in trailer part (after second "%%") of "foo.mly"
It that case, it generates an error like this:
    This expression has type Lexing.lexbuf -> Eg_parse.token
    but is here used with type Lexing.lexbuf -> token

It can be fixed by excluding type specification of start non-terminal
function in "" like this:

    let line (lexfun : Lexing.lexbuf -> token) (lexbuf : Lexing.lexbuf) =
       (yyparse yytables 1 lexfun lexbuf : int)


    let line lexfun (lexbuf : Lexing.lexbuf) =
       (yyparse yytables 1 lexfun lexbuf : int)

If you want, you can view my full source in
