Robert,

Thanks for replying and apologies the explanation wasn't good. I think the
solution is to introduce into the MFC Doc class a member variable m_Version
and load either std::vector<T*>
 or std::vector< shared_ptr<T> > as appropriate. Trying to read one line and
determine the item_version is probably silly.

This issue is closely related to my other post today
([Boost-users][serialization]
Memory leaks even with shared_ptrs) and I'd be grateful if you were able to
give that a look. And a million thanks for the library - it really is an
incredibly useful tool.
