    I get a strange segmentation fault when using object instancing. I've carved down the input file to the following:
    #################
    ObjectBegin 1
    PointsPolygons [ 3 ]
         [ 0 1 2 ]
         "P" [-1 -1 0 1 -1 0 1 1 0 ]
    ObjectEnd
    FrameBegin 0
        Option "trace" "int maxdepth" [2]
        Format 256 256 1

        PixelSamples 2 2
        ShadingInterpolation "smooth"

        Display "foobar.tiff" "framebuffer" "rgba"

        Projection "perspective" "fov" 55
        Scale 1 1 -1
        Translate -1.43773 -0.422992 -31.0313
        Rotate 163.164 -0.118377 0.621475 0.774439
        Scale 1 1 1

        WorldBegin
            Attribute "visibility" "specular" [1]
            Attribute "visibility" "diffuse" [1]
            Attribute "visibility" "transmission" [1]
            Attribute "trace" "bias" 0.005
            Attribute "shade" "transmissionhitmode" ["primitive"]

            AttributeBegin
                Color [1 0.2 0.2]
                Surface "constant"
                ConcatTransform [ 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 ]
                ObjectInstance 1
            AttributeEnd

        WorldEnd
    FrameEnd
    #################

    Oddly, if you change all of those "1"s in the point list, e.g., to "100", the segfault disappears.

      Seems to be a regression. The problem doesn't occur in 2.2.5.
