I think in boost::archive::detail::save_pointer_type<>::invoke (in  
oserializer.hpp) - right after it gets the bpos_ptr from  
register_type.  I presume (but I'm not absolutely certain) that you  
should ALWAYS get back a valid bpos_ptr at this point?

Adding one of those "you might have made this mistake" comments at  
that point with something about BOOST_IS_ABSTRACT on a derived class  
would have shortened my debugging time by DAYS - but I'm not certain  
if that's the main reason for the failure or if anything else could  
cause that kind of failure?

Anyway - thanks for the quick reply and all of the excellent work!
