Boost function "boost::property_tree::ini_parser::read_ini" causing "EXC_BAD_ACCESS (code=EXC_I386_GPFLT)"

[giovacchini.andrea@…]

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
