I was also hit by this on Gentoo with a 64bit host running 32bit static chroot (arm). If it matters at all, I saw it after upgrading the 32bit arm chroot to glibc-2.28, while the host was still on 2.27.
Downgrading again hides the issue. Upgrading the host to glibc 2.28, but keeping the chroot at 2.27 seems to not hit it either.
