Question:

Do pfCycleBuffers work with indexed pfGeoSets?

The reason I ask is this, the man page says this,
     While pfCycleBuffers can be used for generic dynamic data, a
     prominent use is as attribute arrays for pfGeoSets. The function
     pfGeoSet::setAttr accepts pfCycleBuffer memory for attribute
     arrays and the pfGeoSet will index the appropriate pfCycleMemory
     when rendering and intersection testing.

        Currently, pfGeoSets do not support pfCycleBuffer index lists.

Does this mean the index list or the whole pfGeoSet containing the
index list. I am trying to use a CycleBuffer in an indexed GeoSet as
the list of vertices and I am getting coredumps (SEGVs). So the
CycleBuffer's are causing memory to be accessed illegally somewhere,
without CycleBuffers the code runs fine.
