[Buildroot] Xorg Segmentation fault now. Please help

[Lennart Ramberg]

Hello,

After having been away from Buildroot since last year, I'm at it again.
But I had a setback;

With 2014.11 the xorg-server runs allright.
Jumping to 2015.08.1 the xorg-server won't run.
Why might this be? Please help.

Below is a part of my /var/log/Xorg.0.log after I executed 'X',
as well as my defconfig (and there is nothing suspicious in the overlays).
And I did a 'make clean all' first.

Thanks and regards
Lennart
