From 18c2ee0df5fa6679996e40c574d37475be230bd7 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 26 Mar 2012 16:49:23 -0700 Subject: [PATCH] mesa: Create the default (name==0) buffer texture. All that should be needed is that it exists. Fixes segfaults on first _mesa_update_context() with a samplerBuffer-using shader active but without a particular buffer texture enabled.
