I did the following:

        std::for_each ( m_data.begin(),
                        m_data.end(),
                        output << boost::bind ( &Verification_Type_Info::to_String,
                                                boost::bind::_1,
                                                new_indent_limit ) );

I get an error that 

Append_Frame.cpp: In member function 'virtual std::string libreverse::java_module::Append_Frame::to_String(uint32_t) const':
Append_Frame.cpp:50: error: 'boost::bind' is not a class or namespace

Are you sure that the second argument is boost::bind::_1? I found that _1 is declared in boost/bind/placeholders.hpp as:

boost::arg<1> _1;
