So, for you, this diffutils-2023-01-31 tarball fails
  - the stack overflow tests,
  - the localeconv test.

Where for me, on Debian testing (bookworm), downloaded from
https://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-dvd/
with timestamp 2023-01-23, all tests pass.

This indicates that you are hitting bugs in this Debian "testing"
distro, that are already fixed.

Nothing to do in Gnulib, since it's normal for bugs to appear and
disappear in a "testing" (= alpha quality) distro.
