Hi, Experts,

I was trying to run the log basic usage (libs/log/example/basic_usage/main.cpp) example in visual studio. And it crashed at line 
    logging::add_console_log(std::clog, keywords::format = "%TimeStamp%: %Message%");

Stopped at 
        // For compatibility with Boost.Log v1 we recognize %_% as the message attribute name
        const std::size_t len = end - begin;
        if (std::char_traits< char_type >::length(constants::message_text_keyword()) == len &&
            std::char_traits< char_type >::compare(constants::message_text_keyword(), begin, len) == 0)
        {
            m_AttrName = log::aux::default_attribute_names::message();
        }
        else
        {
            m_AttrName = attribute_name(log::aux::to_narrow(string_type(begin, end)));
        }

Anybody has successfully run the example? 
Thanks!

Regards,

Triston
