Confirmed that it also affects the version in bookworm:

  https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/amd64/diffoscope.html

And according to test history, may go back to much earlier versions
(222+)... although there were some other possible FTBFS issues that may
have affected older versions, and I don't immediately see a way to look
at the logs from older versions.

live well,
