bug#58584: 29.0.50; M-w crashes Emacs

[Jacky Li]

I was at eff4a4f49a. In EXWM, using M-w will crash Emacs. The x server
gave an error of not finding the libinput module. I then switched to
dwm, Emacs still crashed after M-w.

I am currently at b9aff5fdb8, everything is fine. I strongly suspect the
bug was introduced in abf683bb03. It should be something related to
putting things into kill buffer related to X. An extra information is
that my Emacs is built with libinput2 support.

Here is the error log from the terminal.

Fatal error 11: Segmentation fault
