[Intel-gfx] The latest Xorg and intel driver segfaults

[Lukas Hejtmanek]

Hello,

I tried to run the latest Xserver and the Intel driver (both current git
head). It segfaults at the startup:

Core was generated by `/usr/local/X11R7.5/bin/Xorg :1.0'.
Program terminated with signal 11, Segmentation fault.
