sdiff output for suspected bad shader

Here is a dump from sdiff of a good shader with no GPU protection faults (left
side) and a bad shader that causes GPU protection faults (right side).  Search
for the pipe character '|' to find the only difference between the two shaders.

I'm not sure yet why this difference would lead to GPU protection faults.
