From 5eca78a00a5de442aaf541a1095d5cfa6b4f45de Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Mon, 1 Dec 2014 14:16:24 -0800 Subject: linker: Wrap access of producer_var with a NULL check producer_var could be NULL if consumer_var is not NULL and consumer_is_fs is false. This will occur when the producer is NULL and the consumer is the geometry shader for a program that contains only a geometry shader. This will occur starting with the next patch.
