Yes. A similar sounding thing was happening a while back - vertex array
counts not matching the expected primitive type, e.g. for quads
vert-count % 4 != 0, if you see what I mean. I added checks for this,
but maybe there are other similar cases.

Another possibility is some state mess up with glEnableClientState();
for colour/normal/etc arrays.

The fact that this happens with any poly primitive is interesting
though. 

Could you try this:

(clear)
(define p (build-sphere 10 10))

(with-primitive p
    (poly-convert-to-indexed))

Indexed polys don't use glDrawArrays, might narrow it down...

cheers,
