What were you trying to do that didn't work?

rhceph8 causing a segfault on IBM Z and Power architectures when compiled using GCC 11 on rhel9 using `-flto=auto` option.

This bug was also observed in other platforms, and now the fix is available in GCC 14. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113359

Could you please backport this fix to GCC 11?

> We tested building rhceph8 with `-flto=auto` option using gcc14 (on ubuntu) and it works fine.

What is the impact of this issue to you?

rhceph builds for ibmz and power are causing segfaults and hence cannot run it on the platforms.

Please provide the package NVR for which the bug is seen:

How reproducible is this bug?:

Reproducible by building rhceph8 on rhel9 using gcc11 with the `-flto=auto` option.
