Using osg::ref_ptr<osgViewer::CompositeViewer> is fine, along as you
don't use it on objects that are created on the stack as C++ will
delete objects on the stack.  You suggestion that change from
ref_ptr<> to C pointer fixing a problem suggests that somewhere along
the line you are mixing things incorrectly, as I don't know you code
it could be a range of things, but I'd guess that the change you've
made suggest a problem elsewhere in your code.
