Mantic s390x install fails: grep-status: *** stack smashing detected ***: terminated
Metadata
Current evaluation
Snapcraft-built Subiquity on Mantic s390x had a missing ELF RPATH, mixing core22's loader with host glibc. Edge core22 worked, but stable core22 still failed on LPAR; the issue remains open.
Suggested action: keep open
Reason: The readelf evidence showed that grep-status revisions 5095 and 5108 differed by a missing core22 library RPATH, and an edge-core22 build passed ISO testing. However, fheimes reproduced the crash on LPAR with the stable-core22 build, after which dbungert explicitly said the issue was being kept open to track the eventual stable-core22 fix.

Issue body
mantic-live-server-s390x ISOs (serial: 20230918) are failing to install, as subiquity crashes with the error reported at the end of this message. By jumping to a shell in the installer live system, I found of that the culprit is grep-status failing to run:
root@ubuntu-server:/# grep-status
*** stack smashing detected ***: terminated
Aborted (core dumped)
What we expect is:
$ grep-status
grep-status: unexpected end of filter.
From the test history I can tell that ISOs with serials:
* Up to 20230915 are working
* From 20230916 up to (at least) 20230918 are failing.
