use musl library + Kernel is one step behind the actual version + setup net-misc/rsync::gentoo in /etc/portage/package.mask is the solution for me. Currently using: net-misc/rsync-3.1.3::musl
Not sure whether this should be in [Overlays] - the ebuild is from the main repo.
(In reply to Jeroen Roovers from comment #1) > Not sure whether this should be in [Overlays] - the ebuild is from the main > repo. Historically yes, we have dealt with this kind of problem in the musl overlay, but blueness and musl team are gradually working to reduce the size of the overlay as time moves forward; to ease maintainability, and as upstreams are merging musl compatibility into their own projects. I believe rsync was on my list of projects to verify the 'progress' of this migration, but often maintainers within Gentoo have been pro-active to merge any patches that do not otherwise affect their packages under eg. glibc et al. We don't / haven't had a separate overlay for eg. uclibc and its successor, so if it is possible to keep packages tidy, especially if we work closely with upstreams we can minimise the patches that Gentoo carries long-term. At this stage, please continue to assign bugs to musl@ but also CC the original maintainer and we can work together to improve the overall situation. TIA!
Okay, please don't hit me. I think the information about musl was important too. I have only one Gentoo System, this use musl and not the default glibc in example. Maybe someone with glibc can make a test?

Not a criticism, I'm not sure Jer was unfamiliar with musl issues, per his comment (#c1) above. I'll check in with base-system@ and see what we can come up with. TL;DR thanks for bringing the bug/issue back into the foreground! :)
Has been fixed in musl overlay, the next release will have the updated g++/clang++ patch included.
