--- Comment #2 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
I think probably these tests failed before the fix, stopped failing with the
fix, and started failing again when the fix was reverted.  So the revision
number is a red herring -- we need to figure out when these tests started
failing before Wilco's fix.
