test case

When running the code on AMD 3650 Mobility it locks the GPU and reboot is necessary. Strangely when run in valgrind it works, also software rendering works.
Comment 1 Michel Dänzer 2016-02-17 02:05:08 UTC
Does the valgrind output contain anything interesting?

How to build the test case? Please don't expect others to run downloaded binaries.
Comment 2 Timothy Arceri 2016-02-17 02:09:52 UTC
This is a bug report following on from a GLSL compiler bug that was fixed. I built the application in that bug with:

gcc mc.c mc_table.c -lGL -lepoxy -lglfw

I also had to add #include <stdio.h> to mc.c

Thanks Timothy.

Only this, since I did not build mesa in debug mode.
