setting LC_ALL avoided the issue: LC_ALL=C emerge strace so it seems to be related to locale which in my case is cs_CZ
strace-4.20/4.22 appears to build fine with LC_ALL=cs_CZ, so assuming something changed to fix it. doesn't seem worth trying to recreate strace-4.11 build setup. if latest versions are still failing for you, feel free to re-open.
