GDB backtrace of crash


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:
xf86-video-ati latest git version (ce9914a)

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

Kind regards
Jan Burgmeier

Might be fixed by http://lists.x.org/archives/xorg-devel/2015-June/046633.html ?

It is fixed with the mentioned patch but if the following patch is also applied the mouse cursor is not rotated.
