[boost] boost::interprocess -- How do I construct a anonymous object ?

Hi, I'm using boost::interprocess (1.37) and would like to construct a couple of anonymous objects. The idea is to construct a named object via Object *o segment.find_or_construct<Object>("theObject")(); and let this one dynamically construct a couple of other objects to which it holds offset_ptrs. On destruction one could simply use segment.destroy_ptr<Object2>( myOffset.get() ); to get rid of these objects. This works fine with objects I constructed with segment.construct<Object2>("GAGA NAME")(); but the reference by name seems to be unnecessary. The doc tells something about constructing and creating of anonymous objects but so far I only find allocators or copy constructors for anonymous objects. Thanks you .... O.
