Created attachment 725647 [details] build.log systemd-248.5 build.log
same with sys-apps/systemd-248.6 Any updates?
same with sys-apps/systemd-249.2 Any updates?
This looks like bug 810937, which we narrowed down to the -ftracer compiler flag. If you want to see a fix for this, you'll probably need to work with the gcc and systemd developers upstream.
Please work with upstream on this.
