Thanks for your quick reply. But unfortunately it didn't help. I had a 
little deeper look into the Archive Concept documentation and found the 
following:
http://www.boost.org/doc/libs/1_47_0/libs/serialization/doc/archive_reference.html#usage
This refers to writing an own archive class and how to avoid compiling, 
linking and execution failures in case of using the macro 
BOOST_CLASS_EXPORT(). I checked in the header-file
     #include <boost/archive/polymorphic_binary_oarchive.hpp>
and the work-around using the macro 
BOOST_SERIALIZATION_REGISTER_ARCHIVE() is implemented there. Still, it 
might have to do something with that. Do you have any further ideas, how 
to solve the problem?
