Hi Nick, I was just reviewing your the code you copied in your earlier message (below) and spotted that the observer_ptr<> was access a local mutex not the GlobalObserverMutex() as it should have been. I've just fixed observer_ptr<> and am currently rebuilding. Could you try the attached include/osg/observer_ptr<>.
I do testing at my end if everything goes smoothly will check the change in. I really don't know if it would fix the problem you are seeing, fingers crossed. Robert.
