Sorry, I didn't go much further. Now it breaks in the following code:

    bool parse_counter_placeholder(path_string_type::const_iterator& it, 
path_string_type::const_iterator end, unsigned int& width)
    {
        return qi::parse
        (
            it, end,
            (
                qi::uint_[phoenix::ref(width) = qi::_1_type()]
            )
        );
    }

The error is:

path_string_type is a flavour of std::basic_string. The code looks pretty much 
like what is in Boost.Spirit docs. Am I doing something wrong?
