Hi Don, This is clearly a bug, could you try the svn/trunk version of the OSG to see if it's still present? If so could you provide an .osg file that reproduces the problem?
As a general note, BIND_PER_PRIMITIVE is bad for performance and portability, it's there for convenience of backwards compatibility but it's really not something I would recommend anyone using.
