Created attachment 116470 [details]
Xorg.0.log, xz compressed

Using

xorg-server 1.17.1
mesa recent git
xf86-video-intel-git 92a2773 with --with-default-accel=sna and --with-default-dri=3

starting steam with dri3 works
starting glxgears with LIBGL_DRI3_DISABLE=1 glxgears works
starting steam with LIBGL_DRI3_DISABLE=1 steam crashes the xserver

I only tried with kwin with opengl compositing with "full repaint" vsync so far.

With a release build the xserver segfaults, with xf86-video-intel with --enable-debug=full it hits an assertion, see attached full debug log.
