Summary0000535: Epel 10.1z x86_64_v2 - QT5 packaging/building wrong - SIGILL crash
DescriptionSeams the new Epel Repo V2 is not working correctly.
Package qt5-qtwayland is doing SIGILL on V2 machine, because it uses V3 ISA.

[root@alma-r510 ~]# rpm -qi qt5-qtwayland
Name : qt5-qtwayland
Version : 5.15.17
Release : 1.el10_1.alma_altarch
Architecture: x86_64_v2
Install Date: Fri 04 Jul 2025 03:23:20 PM CEST
Signature : RSA/SHA256, Mon 30 Jun 2025 04:44:41 PM CEST, Key ID b620c02335d447a6
Source RPM : qt5-qtwayland-5.15.17-1.el10_1.alma_altarch.src.rpm
Build Date : Sun 29 Jun 2025 02:48:13 PM CEST
Build Host : x64-builder04.almalinux.org

readelf -a /lib64/libQt5WaylandClient.so.5|grep ISA
x86 ISA used: x86-64-baseline, x86-64-v2, x86-64-v3

/etc/yum.repos.d/epel.repo
[epel]
name=Extra Packages for Enterprise Linux $releasever from AlmaLinux - x86_64_v2
baseurl=https://epel.repo.almalinux.org/$releasever${releasever_minor:+z}/x86_64_v2/

A search for V3 libraries from libQt5 in Alma V2:
libQt5Core (Also supports v3 on Epel 10.0z)
libQt5Gui (Also supports v3 on Epel 10.0z)
libQt5WaylandClient (NEW - did not support V3 on Epel 10.0z)
libQt5WaylandCompositor (NEW - did not support V3 on Epel 10.0z)

Epel 10.0z x86_64_v2 is OKAY even though some Qt5 libs says using x86-64-v3.

V2 - Should probably be build and tested on x86-64-v2 host...
Steps To ReproduceStart a QT5 program from Epel 10.1z V2 on a V2 machine and it crashes with illegal instruction - SIGILL.
Additional InformationLove that you keep V2 alive for old servers, thanx.
