Yes, this fixed the rendering problem I had.

However, it also seems to have excited a different problem. (Well, there
were a lot of changes in CVS when I updated my source so it may be
unrelated to your fix here.) Attached is a test program which creates a
couple of display lists. The first dl draws a rectangle and translates
the modelview. The second dl just translates the modelview. If there is
a call to glNormal() in the second dl, Mesa segmentation faults in
_tnl_flush_vertices() when the second dl is invoked.

Thanks,

P.S. This behavior arises from trying to "draw" the blank character in
my OpenGL/FreeType 2 text rendering library. See

I just started this project and I'd appreciate any feedback or
suggestions.
