Bug#814982: [xwayland] Reproducible segmentation fault when pluggin new screen



Package: xwayland
Version: 2:1.18.1-1
Severity: important

--- Please enter the report below this line. ---

Hello dear maintainer,

I have been using sid as my main OS since 2001 and over the last couple
of years there has been so few breakage that I didn't even notice that
gnome-session switched to XWayland :) Great work !

I have been experiencing some segmentation faults lately that I thought
were due to Xorg which seems actually  linked to the recent upgrade to
XWayland 1.18.1-1.

When plugging a HDMI screen I get the following segmentation fault :

(EE) Backtrace:
(EE) 0: /usr/bin/Xwayland (xorg_backtrace+0x4e) [0x55cbedb20b0e]

(EE)
(EE) Segmentation fault at address 0x20
(EE)
Fatal server error:
(EE) Caught signal 11 (Segmentation fault). Server aborting

I installed libwayland-server0-dbg but it doesn't seems to yield more
information in the backtrace.

(see attached syslog for full event log there doesn't seems to be more
info in journalctl)

This is always reproducible by either plugging/unplugging the cable or
hitting the Super+P shortcut to switch through xrandr possibilities.

I worked around the issue by downgrading xwayland (and only this
package) to 1.18.0-3.

I also experienced a crash by pluggin an Mini-displayport adapter which
resulted in an intel driver exception see syslog.1 (don't know if it's
relevant just saying if it can help)

Let me know what information you will need to troubelshoot this further.

Thanks a lot in advance
Cheers
LeTic
