After todays update to dev-util/wayland-scanner-1.23.0 and dev-libs/wayland-1.23.0 wayland is no longer usable, dumps core.

Can you try to build mesa+wayland+wayland-scanner with debugging symbols (https://wiki.gentoo.org/wiki/Debugging)?
Created attachment 894739 [details] core dump with debug Emerged with debug symbols.
Dropping back to dev-util/wayland-scanner-1.22.0 and dev-libs/wayland-1.22.0 allows me to run wayland again.
Thanks. ``` Stack trace of thread 1069: #0 0x00007fe4392e755c n/a (libc.so.6 + 0x9355c) #1 0x00007fe4392907b6 raise (libc.so.6 + 0x3c7b6) #2 0x00007fe4392788ba abort (libc.so.6 + 0x248ba) #3 0x00005555d46fc990 n/a (Xwayland + 0x198990) #4 0x00005555d4701539 n/a (Xwayland + 0x19d539) #5 0x00005555d47026c2 n/a (Xwayland + 0x19e6c2) #6 0x00005555d46f9a49 n/a (Xwayland + 0x195a49) #7 0x00007fe439290860 n/a (libc.so.6 + 0x3c860) #8 0x00007fe439c07754 wl_proxy_get_version (libwayland-client.so.0 + 0x8754) #9 0x00005555d45ae3ae n/a (Xwayland + 0x4a3ae) #10 0x00005555d45a8266 n/a (Xwayland + 0x44266) #11 0x00005555d46808b5 n/a (Xwayland + 0x11c8b5) #12 0x00005555d4629937 n/a (Xwayland + 0xc5937) #13 0x00005555d46163ca n/a (Xwayland + 0xb23ca) #14 0x00005555d4617516 n/a (Xwayland + 0xb3516) #15 0x00005555d4623030 n/a (Xwayland + 0xbf030) #16 0x00007fe43927a26e n/a (libc.so.6 + 0x2626e) #17 0x00007fe43927a329 __libc_start_main (libc.so.6 + 0x26329) #18 0x00005555d45a13d5 n/a (Xwayland + 0x3d3d5) ``` I guess we need debug symbols for Xwayland + glibc too.
Let me understand first. Does your compositor crashes or it's only Xwayland? If it's only Xwayland then please also run `WAYLAND_DEBUG=1 Xwayland :5` and attach the log. And if your compositor crashes then we would need a backtrace of your compositor with debug symbols and it's name and version.

(In reply to Leonardo Hernández Hernández from comment #7) > Let me understand first. Does your compositor crashes or it's only Xwayland? Not sure, I get the login screen and is wayland is selected the system freezes on login, all is OK with X11 and/or wayland 1.22. > If it's only Xwayland then please also run `WAYLAND_DEBUG=1 Xwayland :5` and > attach the log. See new journal info and let me know what else I can provide.

I fully agree with everything Chris wrote
I confirm I have the same issue, and rebuilding kwin helps as noted here https://www.linuxquestions.org/questions/showthread.php?p=6505230

I'm still changing machines and not really setup at all but let me at least abidiff the two versions.
