The stack in the log posted in comment #4 is a bit different than the
one in the description:
#0 DamageRegister (pDrawable=0x0,
pDamage=0x7f27a226aa60)
at ../../../miext/damage/damage.c:1774
pScrPriv = 0x7f27a1ba0410
#1 0x00007f27a0fd48a1 in xf86RotatePrepare (
pScreen=0x7f27a1b97030)
at ../../../../hw/xfree86/modes/xf86Rotate.c:171
crtc = 0x7f27a1ba2030
xf86_config = 0x7f27a1ba0410
#2 xf86RotateRedisplay (pScreen=0x7f27a1b97030)
at ../../../../hw/xfree86/modes/xf86Rotate.c:192
xf86_config = 0x7f27a1ba0410
damage = 0x7f27a226aa60
The null pDrawable pointer is obviously wrong, as it's immediately
dereffed in DamageRegister. Perhaps xf86RotatePrepare() needs to check
that before passing it to DamageRegister?
And yes, #1123166 (+dupes) seems the same as this.
