This happen with mesa compiled with -O3. With -Og is perfectly fine. Kernel: 3.12.18 Mesa: git (1646f4d0fb0efec04dce62b6dd4d974206acc8ac) Card: Radeon HD 6550 (3870K APU)

--- Comment #1 from Alex Deucher agd5f@yahoo.com --- Is this only an issue with -O3?

--- Comment #2 from Alex Deucher agd5f@yahoo.com --- nevermind.

--- Comment #3 from Marek Olšák maraeo@gmail.com --- I think the result of this test is random. It's also random on radeonsi.

--- Comment #4 from David Heidelberger (okias) david.heidelberger@ixit.cz --- it's random with -O3 or just random?
if you want some more testing on 6550D, let me know

--- Comment #5 from Marek Olšák maraeo@gmail.com --- I always compile with -O2 and the test result is random pass/fail.
https://bugs.freedesktop.org/show_bug.cgi?id=78669
--- Comment #6 from David Heidelberger (okias) david.heidelberger@ixit.cz --- try with -O3, then it's permanently
PIGLIT: {'result': 'fail' }
I tried: while true; do /home/okias/projects/piglit/bin/gl-3.2-layered-rendering-clear-color-all-types 3d single_level -fbo -auto | grep result; done
and always fail

--- Comment #7 from David Heidelberger (okias) david.heidelberger@ixit.cz --- with -O between -Og, -O0 and -O2 it gives 1:300 - pass:fail Chances for pass are increased by running or turning off any GL app.. for this case I always get one or two "pass".
With CFLAGS="-ggdb -pg -g -Og -gdwarf-2 -gstrict-dwarf" I mostly getting more pass for turning GL app on/off (about 3-4)
Command to test: $ while true; do sleep 0.03 && /projects/piglit/bin/gl-3.2-layered-rendering-clear-color-all-types 3d single_level -fbo -auto | grep pass; done
