--- Comment #18 from Tom Stellard tstellar@gmail.com --- Created attachment 116227 --> https://bugs.freedesktop.org/attachment.cgi?id=116227&action=edit 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.
