Re: GLU.Tessellator crashes

Hello,

I can't reproduce this behaviour (though I didn't try very hard).
Could you send some specific code which produces bus error on your setup?

By the way, you make a Storable instance for () yourself:

instance Storable () where
  alignment _ = 1
  sizeOf _ = 0
  poke _ _ = return ()
  peek _ = return ()
