xserver log, backtrace
After upgrading xserver to the latest git version
(Adam Jackson,2019-11-13)I get a segmentation fault.
See the attached Xorg.0.log with the backtrace.
In -modesetting, so please report the issue to gitlab.freedesktop.org, if you can quickly bisect as wel (there were only a few commits) that would help even more -- though they are all glamor/modesetting...
