9585	program_option::environment_iterator moves past terminating NULL pointer	abel@…	Vladimir Prus	"The get() method increments m_environment outside of the else scope:

        void get()
        {
            if (*m_environment == 0)

                found_eof();

            else {

                std::string s(*m_environment);

                std::string::size_type n = s.find('=');

                assert(n != s.npos);

                value().first = s.substr(0, n);

                value().second = s.substr(n+1);
            }

            ++m_environment;
        }

This means the iterator will move past the terminating pointer. A simple fix seems to include the increment in the else's scope."	Bugs	closed	To Be Determined	program_options	Boost 1.55.0	Problem	fixed
