Created attachment 15089 [details] Xorg conf file Hi, I'm using latest git DRM, Mesa, Xserver and intel drivers. When trying to run any GL app (I've tried glxinfo and glxgears) I get a segmentation fault with this backtrace (bt and bt full output provided). There are no special messages in dmesg or in Xorg standard output. I'll attach xorg.conf and xorg.log (gdb) run Starting program: /usr/bin/glxinfo (no debugging symbols found) (no debugging symbols found) [Thread debugging using libthread_db enabled] [New process 6463] name of display: :0.0 [New Thread -1212221776 (LWP 6463)] Program received signal SIGSEGV, Segmentation fault.

This should be fixed, please try the latest git. In the future, when posting bug reports against builds from git, include the exact git revision that you've built, thanks.
Okay, I'll state the commit name, thanks I can't test this currently because of the bug 15010, but I'll test and close as soon as the 15010 is fixed.
the bug is still there, commit e80a2888bb8930b19f278700d29bc7a2d6cab5f5 : 0x00000000 in ?? () (gdb) bt #0 0x00000000 in ??

Ah, I see the problem, I was testing the wrong pointer for NULL. Try out commit 98e13fecd... The crash triggers because libGL is trying to load an incompatible version of the dri driver, so you should recompile and reinstall the drivers too.
fixed, thanks!
