Thanks for reply,

All classes a, b, c and d are actually defined within one dll (one module). I forgot to mention it. I can do this following thing:

d* pD = mew d();

and then ar & boost::serialization::make_nvp("item", pD);

but c* pD = new D(); ar & boost::serialization::make_nvp("item", pD);

does not work at all! It throws this strange type of exceptions which I cannot handle at all.

This should work if d is exported BOOST_SERIALIZATION_EXPORT(d)

Another problem is that if I do the first version the member m_key variable of true_type in the call

const boost::serialization::extended_type_info * true_type = i.get_derived_extended_type_info(t);

again This should work if d is exported BOOST_SERIALIZATION_EXPORT(d) Robert Ramey
