Created attachment 119031 GDB backtrace of crash

Hi,

My setup is the following:

PC: HP T620 Plus with two AMD graphics card Monitors: 3 Dell 4k Monitos running at 1920x1080. Two are attached to the primary card and one to the secondary card.

After activating all displays with "xrandr --setprovideroutputsource" xorg crashes with a segfault when display connected to the secondary GPU is rotated.

The following versions were used: Xorg-1.17.2 xf86-video-ati latest git version (ce9914a) mesa-11.0.0 libdrm-2.4.64 libLLVM-3.7

It does not matter if using DRI2 or DRI3. It does not matter if ColorTiling2D is on or off.

Kind regards Jan Burgmeier
