Hi,

Pulled this from a larger application to isolate to the problem:  -d 
./tmp or -d "./tmp" doesn't go to directory string but is with the 
positionals:

#include <stdlib.h>
#include <iostream>
#include <exception>
#include <string>
#include <cstring>
#include <memory>
#include <fstream>

#include "boost/program_options.hpp"

int main(int argc, char** argv) {
     try {
         boost::program_options::positional_options_description p;
         p.add("input-file", -1);
         std::string directory = "./";
         boost::program_options::options_description visible("Allowed 
options");
         visible.add_options()
                 ("input-file", 
boost::program_options::value<std::vector<std::string>>(), "input files 
can be *.xml, *.pdb, *.mol2, *.mtz, *.cif, *.csv, and *.sdf. Csv and sdf 
formats are for NMR calculations. csv lists the atoms for which the 
shifts will be computed. 1st line containts the Header: 
\"Chain\",\"Residue ID\",\"Sequence\",\"Atom Name\",\"Unbound 
ppm\",\"Bound ppm\". Then atoms may be listed i.e 
\"A\",\"MET\",231,\"CE\",10.30,10.50. sdf file contains the ligands for 
a CSP calculation. ")
                 ("directory,d", 
boost::program_options::value<std::string>(&directory)->implicit_value("./"), 
"Directory for publishing output.")
                 ;
         boost::program_options::options_description all("Allowed options");
         all.add(visible);//.add(hidden);

         boost::program_options::variables_map vm;
boost::program_options::store(boost::program_options::command_line_parser(argc, 
argv).options(all).positional(p).run(), vm);
         boost::program_options::notify(vm);
         std::vector<std::string> fileList = vm["input-file"].as < 
std::vector < std::string >> ();
                 for (unsigned int fileListIndex = 0; fileListIndex < 
fileList.size(); fileListIndex++) {
                     std::cout<<" "<<fileList[fileListIndex]<<" 
"<<std::endl;
                 }

     } catch (std::exception& e) {
         std::cout << e.what() << std::endl;
     }
     return 0;
}

Built with g++ 4.9.0 on Linux frodo.quantumbioinc.com

2015 x86_64 x86_64 x86_64 GNU/Linux

g++ -fPIE -std=c++11 -I${BOOST_HOME}/include

And run as

./main 2-aminoethanol.pdb -d ./tmp

which results in

  2-aminoethanol.pdb
  ./tmp

This code had been working with 1_57_0.  Some change in the API I need 
to adjust for?
