After doing some commands in Emacs/GTK, emacs and my window manager crashes and I get logged out. As I write this I'm at `/bin/emacs -nw -Q`, because emacs crashed while reporting bug. I've reproduced it several times with the following commands: 1. `/bin/emacs -Q` 2. `C-h C-p` for PROBLEMS-buffer 3. `M-x org-mode` enable org-mode 4. Tab (`org-cycle`) on headline 5. Emacs and window manager hangs and emacs get core dump But I have also had the crash when running: 1. `/bin/emacs -Q` 2. `M-x report-emacs-bug` 3. scroll down line by line with `C-n` to the bottom 4. scroll up line by line with `C-p` 5. When point was at the left parenthesis in the `Features` section same crash. Or: 1. `/bin/emacs -Q` 2. `M-x report-emacs-bug` 3. `C-x C-f emacs.bug` (File where I saved journalctl entry) 4. `C-x space` and scroll down with `C-n` 5. Somewhere in the middle of file the crash happened. This started yesterday as I updated both Emacs, Kernel, X as well as some other packages with `pacman -Syu`. I have some other crashes from other programs in journalctl. The system seems to be stable when not running emacs (or only `emacs -nw`). Please let me know if you need journal or pacman logs.
