I don't see any problem with the code snippet. Maybe you want to make small test which we run here.
ok here it comes. It looks artificial, but it is just a simplification of a case. It gives an access violation after thhe load, when it tries to destroy the object.
OK - here are the changes I made in order for your example to work: the main one is to enclose the output in {} to be sure that the xml archive dtor is called. The ensures that the xml file contains the trailer tags. This was what calling the load exception. I discovered this by visually inspecting the xml file to and it was obvious to see that it wasn't terminated correctly. I just commented out some stuff that made no sense to me. Robert Ramey int main() { BoostExample obj; std::stringstream sstr; //save make sure dtor is called on the oa // by enclosing it in {} { boost::archive::xml_oarchive oa(sstr); oa << BOOST_SERIALIZATION_NVP(obj); } //triggers a load exception // what is this for? #if 0 std::string str = sstr.str(); boost::replace_all(str, "<m_ptr1>", "<m_ptr1"); sstr.str(str); //load obj.m_ptr.reset(); obj.m_ptr1.reset(); sstr.seekg(0); #endif //load try { boost::archive::xml_iarchive ia(sstr); try { ia >> BOOST_SERIALIZATION_NVP(obj); } catch (boost::archive::archive_exception& /*re*/) { ia.delete_created_pointers(); } } catch (boost::archive::archive_exception& /*re*/) { } }
