[boost] [serialization] BOOST_CLASS_EXPORT and module boundaries

Looks like BOOST_CLASS_EXPORT does not work across library boundaries, or I 
misunderstand how it should work.

My understanding was that as you declare derived class, you also invoke 
BOOST_CLASS_EXPORT on it, and now you can save pointers to that class 
everywhere.

But this does not work in my tests. Unless I use BOOST_CLASS_EXPORT in the 
code which does actual saving, I get:

/space/NM/boost-serialization/boost/serialization/oserializer.hpp:297: static 
void boost::serialization::detail::save_pointer_type<Archive, 
TPtr>::polymorphic<T>::save(Archive&, const T&, const 
boost::serialization::basic_oserializer*) [with T = B, Archive = 
boost::archive::text_oarchive, TPtr = B*]: Assertion `__null != vp' failed.

Test case attached. Am I doing something wrong?
