Journalctl traces

After upgrading MESA to version 18.1.1 Primus (bridge for Bumblebee, the NVIDIA
Optimus implementation) segfaults while trying to use applications that require
GLX.Running same applications with Intel and VirtualGL (another bridge for
Bumblebee that runs slower than Primus) works fine.After downgrading to Mesa
18.0.4 everything starts working again.Applications' logs don't say much.
The issue can be reproduced by:
1)Installing Bumblebee 3.2.1, MESA 18.1.1 and primus 20151110
2)Running any GLX application with primusrun
