Yes, it's bug but I'm not sure if it is bug in udns or in gcc. I'd like to ask you for add comment to bug https://bugs.gentoo.org/show_bug.cgi?id=400905 with your emerge --info. It looks gcc's optimizer on SPARC, even with -O2, do something unwanted in udns. Additionally I'll notify upstream. Marcin
