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
