From ddba509c16c4cb0630a4f4841b31953f02be6b3f Mon Sep 17 00:00:00 2001 From: =?utf8?q?St=C3=A9phane=20Marchesin?= Date: Sun, 9 Oct 2011 16:49:19 -0700 Subject: [PATCH] mesa/st: Check for a NULL _LinkedShader[i] before using it. The rest of the linker/glsl translation code checks for NULL, so I suppose we should check here too. Fixes crash on exit with i915g instanced drawing.
