shared_pointers (boost and std) are not serializable as things stand.
[...]
This was OK .... until now when we have a new shared_ptr to deal with.
The real solution is to enhance the serialization API so that the code
used for implementing boost::shared_ptr can be applied to other
data types which are otherwise unserializable. Unfortunately, this
is a non-trivial task which I have yet to get to.
Maybe it's time to recover archive helpers as we discussed some years ago:
I won't repeat my arguments, but I think helpers were a nice general solution to implement non-trivial serialization for types with shared semantics and
other, hard to crack cases.
