Well... consider:

    std::cout << ( std::string ( "0001" ) > std::string ( "000" ) ) << '\n';
    std::cout << ( std::string ( "1110" ) > std::string ( "111" ) ) << '\n';

    std::cout << ( std::string ( "0101" ) > std::string ( "000" ) ) << '\n';
    std::cout << ( std::string ( "1010" ) < std::string ( "111" ) ) << '\n';

    std::cout << ( std::string ( "000111" ) < std::string ( "111" ) ) <<
'\n';
    std::cout << ( std::string ( "111000" ) > std::string ( "111" ) ) <<
'\n';

But I guess, problem solved:
http://en.cppreference.com/w/cpp/algorithm/lexicographical_compare and
comparison of boost::dynamic_bitsets<> should neither throw or assert.
