c++ - Debug Boost.Serialization Address Tracking -

roughly speaking, have object o , pointer object po = &o, serialize this:

// somewhere ar & o; // somewhere else, after somewhere ar & po;

when serializing po, boost.serialization should find has serialized o , not serialize *po again. have situation library fails @ discovering situation , instead serializes o twice.

unfortunately, attempts @ reproducing behaviour in simple illustration failed, , original code way big posted here. instead of solution problem, inquire pointer relevant code section in boost.serialization tracks addresses , determines whether pointer needs "deeply" serialized or not. hope can debugging myself.

of course, best guesses error might welcome, don't want strain crystal balls much. ;-)

btw, utilize boost::archive::text_oarchive if relevant.

the code section in question save_pointer() function in basic_oarchive.

boost.serialization uses 2 characteristics check whether object has been serialized: object address , object type. address part obvious, , if think type part makes sense. problem did not think , checked 2 addresses in question same. indeed held true, since types different, serialization library assumed 2 different objects.
