This crash stopped happening after I added the following hack:
--- a/src/mesa/drivers/dri/r300/r300_cmdbuf.c
+++ b/src/mesa/drivers/dri/r300/r300_cmdbuf.c
@@ -424,7 +424,7 @@ static void emit_zb_offset(GLcontext *ctx, struct
radeon_sta
uint32_t dw = atom->check(ctx, atom);
rrb = radeon_get_depthbuffer(&r300->radeon);
- if (!rrb)
+ if (!rrb || (rrb->cpp == 0))
return;
zbpitch = (rrb->pitch / rrb->cpp);
However, this did result in a couple of "no rrb" messages in my output log.
There were also a lot of artifacts present (see attachment), although that may
be a separate bug.
