[osg-submissions] Off-by-one error in osgUtil/RenderBin.cpp?

[Andrew Bettison]

I have an application which provokes the following warning every time it 
invokes osgUtil::SceneView::draw():

    Warning: State::removeStateSet(4294967295) out of range

If I change line 384 of osgUtil/RenderBin.cpp from

*    if (numToPop>1) --numToPop;*

to
*
    if (numToPop>=1) --numToPop;*

then the warning goes away.  I haven't noticed any other effects of this 
change.

If you want, I can try to produce a minimal node graph file that 
provokes this warning when viewed with /osgviewer/, but it occurs to me 
that since it's such a simple change, you might merely need to inspect 
the code to decide whether or not it's just a simple off-by-one error.

Regards,
Andrew Bettison
