Please do replace the current kludge that is sensitive to: - compiler behavior that can change with new versions - compiler gcc/clang - optimization options - linux(KVM) - non-linux (no-KVM) build - community not actively testing non-linux no-kvm build with optimization on clang My patch replaced it makes it work.
