Thanks for the defect report. Please submit a bug at
http://sourceforge.net/tracker/?group_id=5704&atid=105704 , maybe with
the contents of your previous email also.

Unfortunately I can't give the defect much attention as I now only work
with SableCC in my spare time, but please keep track of any patches you
make so I can apply the fixes!

Are you instantiating the Parser using the custom Lexer and Parser like
the code in org.sablecc.isoc.Compiler?

       /* HashSet to keep track of typedefs */
        HashSet typedefs = new HashSet();
        Hashtable enumIdentifiers = new Hashtable();

        try {
            Parser p =
            new CustomParser (
                new CustomLexer (
                    new PushbackReader (
                        new InputStreamReader (System.in), 1024),
                    typedefs, enumIdentifiers),
                typedefs, enumIdentifiers);

            Start tree = p.parse();
            tree.apply(new ASTPrinter());
        } catch (Exception e) {

            System.out.println(e.getMessage());
        }

Cheers,

Roger
