It's not a fix. As far as I can work out the bug is a dangling
osg::State::_vas pointer ending up referring to a newly created
VertexArrayState object. It's only fluke that an issue is appearing
for VAO. If I am correct and it's an dangling pointer then the
problem has the potential existing more widely than VAO, the VAO side
is a symptom not the cause.
I have been looking into how to properly resolve this dangling pointer issue.
Robert.
