File: serialization/oserializer.hpp, line 394:
            if(NULL == true_type){
                boost::serialization::throw_exception(
                    archive_exception(
                        archive_exception::unregistered_class,
                        true_type->get_debug_info()
                    )
                );
            }

I think, that if true_type is NULL, then true_type->get_debug_info() is UB.
