----------------------------------+---------------------------
 I have a simple source like this that build and executes correctly under
 Windows 10 with Visual Studio 2015 but throws "EXC_BAD_ACCESS
 (code=EXC_I386_GPFLT)" under OsX 10.11.3 with Xcode 7.2.1:

 {{{
 #include <boost/property_tree/ini_parser.hpp>
 #include <boost/property_tree/ptree.hpp>
 #include <boost/property_tree/json_parser.hpp>
 #include <iostream>
 using namespace std;

 int main(int argc, char* argv[])
 {
     if (argc != 3)
     {
         std::cerr << "Usage: program rootPath iniFileName" << std::endl ;
         return 1;
     }

     string mainPath(argv[1]) ;
     string iniFileName(argv[2])  ;

     boost::property_tree::ptree pt;
     try
     {
         boost::property_tree::ini_parser::read_ini(mainPath + iniFileName,
 pt);
     }
     catch(const boost::property_tree::ptree_error &e)
     {
         cout << e.what() << endl;
     }

      return 0;
 }
 }}}


 This is the stack trace:

 Problem comes from "stream.imbue(loc);" line in ini_parser.php from this
 function:


 {{{
     template<class Ptree>
     void read_ini(const std::string &filename,
                   Ptree &pt,
                   const std::locale &loc = std::locale())
     {
         std::basic_ifstream<typename Ptree::key_type::value_type>
             stream(filename.c_str());
         if (!stream)
             BOOST_PROPERTY_TREE_THROW(ini_parser_error(
                 "cannot open file", filename, 0));
         stream.imbue(loc);
         try {
             read_ini(stream, pt);
         }
         catch (ini_parser_error &e) {
             BOOST_PROPERTY_TREE_THROW(ini_parser_error(
                 e.message(), filename, e.line()));
         }
     }
 }}}


 Since I can't see how my code can generate this kind of problem I think it
 is a Boost bug
