I tried this on a different platform, here ppc64el and ipa-client-install does not seg fault there:
ubuntu@p10d-lpar06:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy
ubuntu@p10d-lpar06:~$ arch
ppc64le
ubuntu@p10d-lpar06:~$ sudo ipa-client-install
This program will set up IPA client.
Version 4.9.8
...
And I also found LP tickets where people could run it on amd64.
Hence I strongly believe that this is a s390x specific problem.
