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
