std::strings are special in that they are considered primitives. If you look at ser../string.hpp you'll notice that the serialization code is commented out and that the serialization trait for the std::string class is set to "primitive". There is code that specifically handles std::string. The reason is that the std::string is used in the archive header and due to chicken and egg issues, I chose to make strings prmitives.

  I have a custom stream that I am adaptiing to, so I build oarchive and iarchive classes derived from boost::archive::detail::common_xarchive according to the documentation. I have a function that looks like the following to handle the specifics of loading and saving.

  template<class T>
  void load(T & t)
      // load data...

  This seems to work for everything except std::string's. I noticed it when writing out a std::map<std::string, std::string>. The map is handled properly by the boost/serialization/map.hpp routines, but the strings are sent to my load function instead of being handled by boost/serialization/string.hpp.

  Any insight in to what I could possibly be doing wrong would be greatly appreciated.
