Thanks, Robert

First of all I didn't mean to criticize, it's just that for me things
are not as clear because I'm not an  expert, so it's not like I don't
buy it, I just don't see it. But I'll take your word for it. So a const
cast it is. If you can indulge me a little bit more, though, what I did
to fix my problem, that works on the tutorial example as well, was to
add:

BOOST_CLASS_TRACKING(MyClass, boost::serialization::track_never)

If I understand it right, I would want object tracking only if my
classes somewhere in their implementation use pointers to keep track of
members. I don't do that but I do use STL containers in several places.
Am I liable to break serialization by using that macro? If you think I
should just RTFM, please do so (I think I did, though)

Thanks again for a very useful library
