I think it might be the function I've cut out below. Try using boost:serialization::make_nvp in place of the macro: ar & boost::serialization::make_nvp("base", boost::serialization::base_object<base>(*this)); The macro uses the parameter as the name for the XML element. Because it's a templated type then the angle brackets are probably included in the name, which would be invalid XML syntax.
