 It crashes before it can construct the exception. The code I'm looking at
 (boost/archive/detail/oserializer.hpp, line 376) is:

 if(NULL == true_type){
         boost::serialization::throw_exception(
                 archive_exception(
                         archive_exception::unregistered_class,
                         true_type->get_debug_info()
                 )
         );
 }

 Evaluating the second parameter to archive_exception will dereference a
 null pointer.
