[2022-11-03T16:56:19+0100] [ALPM] upgraded sudo (1.9.11.p3-1 -> 1.9.12-1)
This may be a usefull hint 
Do you use btrfs ? Then verify all checksums with scrub !
I don’t use brtfs and reinstalling does not make any change
su and sudo are two different commands from two different packages.
Unless you post coredump with debug symbols or at least strace, it’s anyone’s guess.
Mine: you have unmerged .pacnew somewhere in /etc/pam.d/ or you changed something at some point. If not pam, then shadow or somewhere like that. Wouldn’t be surprised if some file is missing somewhere.
You can also try reinstalling any of the following: util-linux, pam, pambase, shadow.

[dellg5 marco]# strace su - marco

Nothing catches my expert eye. (I kid, I kid. I know strace just as much as the next guy in grocery store.)
Probably something in this child thread…
wait4(6723, [{WIFSIGNALED(s) && WTERMSIG(s) == SIGSEGV && WCOREDUMP(s)}], WSTOPPED, NULL) = 6723
Try:
strace -fo strace.txt su - marco
and upload strace.txt.
The transfer you requested has been deleted.
I wanted to have a look at it - and downloaded it.
Now I uploaded it again.

And? What is your conclusion? 
If you know german:
Ich habe wie ein Schwein ins Uhrwerk geguckt.
If you don’t know german:
I started to read the manual page for strace
but as of now I could not make heads or tails of it.
Cheers!
My german is as good as my strace. 
And well… strace doesn’t really help with segmentation faults…
What happens (and might be totally unrelated) just before SIGSEGV is, there are bunch of locale files tried to open:
156564 openat(AT_FDCWD, "/usr/lib/locale/en_US.UTF-8/LC_CTYPE", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
156564 openat(AT_FDCWD, "/usr/lib/locale/en_US.utf8/LC_CTYPE", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
156564 openat(AT_FDCWD, "/usr/lib/locale/en_US/LC_CTYPE", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
156564 openat(AT_FDCWD, "/usr/lib/locale/en.UTF-8/LC_CTYPE", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
156564 openat(AT_FDCWD, "/usr/lib/locale/en.utf8/LC_CTYPE", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
156564 openat(AT_FDCWD, "/usr/lib/locale/en/LC_CTYPE", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
156564 --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=NULL} ---
Shouldn’t really matter (I don’t have those files at those paths as well), but it’s weird to me because if I try to do the same strace I never get these locale calls at all (tried on 4 different systems). And there are plenty of other openat(…some locale paths…) calls before as well.
Another thing that seems to be connected to locale is if we look at gdb stacktrace:

last thing before it goes to libc is #5 0x00007f59ce2f2cbc _rl_init_locale (libreadline.so.8 + 0x36cbc).
So my new hypothesis: it’s either something with locale or with terminal itself.
@mgazzin, so look at @andreas85’s link. And if that doesn’t work, try:
- running it directly in tty or some other terminal
- change to different shell
- check your locale/env vars/$HOME dotfiles/etc
more EDIT:
@mgazzin can you also post:
pacman -Q readline
readelf -a /usr/lib/libreadline.so.8 | grep _rl_init
Just asking because I have this function at offset 0x36c70 on arch (readline 8.2.001-1) and on manjaro (readline 8.2.0-1).
Nevermind, that offset ( 0x36cbc) just points further into the function.
I do not have any /etc/sudo.pacnew :
[dellg5 mgem]# ls -lad /etc/sudo*
-rw-r--r-- 1 root root 4557 Oct 23 16:59 /etc/sudo.conf
-r--r----- 1 root root 3319 Oct 23 16:59 /etc/sudoers

-rw-r--r-- 1 root root 9800 Oct 23 16:59 /etc/sudo_logsrvd.conf
I believe it is something in locale configuration.
One year back I had to switch to German and few months back I switched back to English. For few months everything was ok. I found this in locale.gen:
I commented out and made:
# locale-gen
I need to check if it works at next reboot. If doesn’t I will make a fresh installation.

do you have more experience in groceries ? 
Yes. Buy green bananas.
