Jeff,
Although, I am having problems with my VC71 MFC application reporting memory leaks of a 24byte block corresponding to each shared_ptr loaded from an oarchive.
You probably mean "loaded from an iarchive". Anyway, due to the modifications I've made in our local code base of boost::serialization I had a bit of a look through the code. I'm not sure, but the memory leaks you experience could possibly be related to the fact that basic_iarchive::delete_created_pointers is never called. Maybe you can add a call to this function yourself somewhere in your application (delete_created_pointers is a public member function of basic_iarchive) and see if the memory leaks disappear. Note that this is just a guess on my part, as I haven't had time to look at all the code in detail. In reference to the example you posted, you could change it to not use an empty shared_ptr but actually allocate an object for it and then change the deserialization code to: if( lIn.good() ) { boost::archive::xml_iarchive ia( lIn ); ia & boost::serialization::make_nvp( "SomeClass", lSomeClass ); ia.delete_created_pointers(); } Regards, Martin TAB Austria Industrie- und Unterhaltungselektronik GmbH & CoKG http://www.tab.at
