Hi,

In the last week I have been playing with the spec-viewperf programs and
(at least on my computer) I get very strange results with "DRV" (the
oil-drilling-platform):

With Mesa in software-mode (latest CVS) I do not see almost anything. It
looks like the triangle-culling was killing the wrong side of the objects.

If I use XFree-4.2 hw-rendering (Radeon VE), I see many more pipes though
the ladders are not visible until the test uses only lines, instead of
filled polygons. Also here there still seem to be some mistakes either
with clipping (polygons at the border of the screen look strange) or
culling (very small polygons seem to be missing) (or both).

But then I went a step further and compiled the view-perf with the
switches "-DMP" and "-lpthread", which seem to enable threads.
While all other tests work (as far as I can tell), DRV crashes now. In
Software-mode I get a segmentation fault and in hardware mode it says
"RadeonSwapBuffers error: some number".

Can anybody reproduce these problems?
