Hi Robert,

The problem in your example is your circular dependency. Right off
the bat you've created a memory leak as this subgraph. The fact that
you then hit a circular reference in the internal patent management is
perhaps not too surprising either.
Right, although I'm not really worried about the cycles as this is just
for a small short-running tool.
You shouldn't create ownership cycles like this in your data
structures, instead you need to break them vai the use of
osg::observer_ptr<> or C pointers. Once you do this you'll probably
avoid all the other problems you are introducing. If your case I'd
create a UserData object that has a observer_ptr<> to the node you
want to refer to, this way you should be able attach it anywhere in
your scene graph without issues without onwership.
I indeed now use a Referenced-subclass that has a pointer to the actual
class I want to reference.
