Description of problem:
When using vrrp_version in /etc/keepalived/keepalived.conf, the logs show "Invalid VRRPv3 checksum". This happened when all servers were EL9, or a mix of EL8/EL9. (There is no issue when all servers were EL8).

Version-Release number of selected component (if applicable):
AlmaLinux 9.2
Keepalived 2.2.4-6.el9

How reproducible:
Always

Steps to Reproduce:
1. Install keepalived on at least 2 servers
2. global_defs, use vrrp_version 3

Actual results:
"Invalid VRRPv3 checksum" in the logs, as well as servers fighting over the primary server

Expected results:
Server with highest priority being the primary, without "Invalid VRRPv3 checksum" in logs

Additional info:
It was suggested to me to try compiling with -fno-strict-aliasing, to see if related to https://github.com/acassen/keepalived/issues/2160. I was unable to reproduce the issue afterwards, so it may be related.
CFLAGS="$RPM_OPT_FLAGS -fno-strict-aliasing"
