MyClass is not abstract. it has virtual functions, but no pure virtual 
functions. if i use that macro however, the error goes away, but i then get 
this runtime assertion failure when it tries to serialize out.

/usr/local/include/boost-1_32/boost/archive/detail/oserializer.hpp:432: 
static void boost::archive::detail::save_pointer_type<Archive, 
TPtr>::polymorphic<T>::save(Archive&, const T&, const 
boost::archive::detail::basic_pointer_oserializer*) [with T = MyClass, 
Archive = boost::archive::binary_oarchive, TPtr = MyClass*]: Assertion 
`__null != bpos_ptr' failed.
