From: "Xu,Randy" <randy...@intel.com>
The crash is due to NULL pColorBlendState, which is legal if the
pipeline has rasterization disabled or if the subpass of the render pass
the pipeline is created against does not use any color attachments.
Test: Sample subpasses from LunarG can run without crash
