By default boost::bind makes a copy of its arguments, but you can use 
boost::ref to make it store a reference to thrd_grp instead:

          boost::bind(&boost::thread_group::create_thread, 
boost::ref(thrd_grp),

Since create_thread is a member function, a pointer to thrd_grp will work, 
too:

          boost::bind(&boost::thread_group::create_thread, &thrd_grp,
