In particular, if I want to use boost::ptr_vector, then do I need to have stateful allocators (both the normal container allocator, and the clone_allocator)?
Sorry, I'm not familiar with ptr_containers. If you can give me some hints on what's clone_allocator for, I'll be glad to help you to make ptr_container compatible with shared memory allocators. Just one issue: shared memory does not support virtual functions, so I don't think polymorphic cloning will be usable at all.
Currently the clone-allocators are a stateless customization point for cloning. It tells the containers how to clone the (indirectly) held pointees. I guess support for virtual functions is needed, except for the most trivial cases. So what does it mean exactly, that shared memory does not support virtual functions? Can I never call a virtual function on an object if that object's memory is shared? (In which case I'm a bit puzzled :-)) -Thorsten
