It turns out bzflag doesn't always segfault, only if I try to turn the
"Blending" option off in the "Display settings" menu. The segfault is
due to doing a procedure call to a NULL function pointer at line 279
of Mesa/src/mesa/tnl/t_vb_render.c in the run_render() function:
tnl->Driver.Render.Start( ctx );
i.e. it seems that tnl->Driver.Render.Start is NULL.
I notice that r200_swtcl.c does this in radeonFallback():
tnl->Driver.Render.Start = r200RenderStart;
Is that statement what should be being executed to initialize
tnl->Driver.Render.Start? Or does that only apply for r200, not r300?
Paul.
