 If you have an option that allows multiple tokens and give that option at
 both command line and config file, only the tokens listed on the command
 line are saved.

 I fixed this issue by changing:
 {{{
             // If option has final value, skip this assignment
             if (xm.m_final.count(name))
                 continue;

             const option_description& d = desc.find(name, false,
                                                       false, false);
 }}}
 to:
 {{{
             const option_description& d = desc.find(name, false,
                                                       false, false);

             // If option has final value, skip this assignment
             if ((xm.m_final.count(name)) && (d.semantic()->max_tokens() <=
 1))
                 continue;
 }}}

 in boost::program_options::store() function in the file
 boost/libs/program_options/src/variables_map.cpp.
