Hi Tugkan,
Thanks for the example code. I've enable the compile of each of the
three #if #elif sections in term and they are run and exit cleanly.
Nothing appers to be amiss. Are you using the latest OSG in SVN?
W.r.t when its safe to modify the scene graph, its safe to modify any
DYNAMIC scene graph leaves (Drawable + StateSet) any time outwith the
Viewer::renderingTraversals() call. When you aren't running
DrawThreadPerContext or CullThreadPerCameraDrawThreadPerContext there
isn't even the limitation of modification of just DYNAMIC scene graph
leaves.
As to what might be amiss at your end I don't know.
Robert.

I've worked more on the subject and repeated the crash in a simple
application derived from osgviewer. You can find it attached. Unlike our
application it also happens in SingleTreaded mode here. As far as I
understand the new threading system it should be safe to access the
scene graph outside the frame() method. And anyway it is single threaded
mode here.
As I was working on this problem I ran into another problem also. If I
call viewer.getCamera()->getOrCreateStateSet()->setDataVariance(
osg::Object::DYNAMIC ) before the main loop and switch to
DrawThreadPerContext mode using 'm' application freezes.
See if blocks at the end of the main(). First block is for freezing and
the second block is for crash.
