At the moment I can only provide a backtrace, a very simple test program doesn't crash (of course). I'll try to come up with something later or tomorrow. What might be interesting is that boost::program_options::variables_map derives from std::map. Here's the backtrace: Program received signal SIGSEGV, Segmentation fault.
