Well, I found via Google a command that could tell me the first revision
of a branch.  Apparently revision 81976 is the first revision of the 4.2
branch:

------------------------------------------------------------------------
r81976 | pd | 2022-03-25 07:02:01 +0800 (Fri, 25 Mar 2022) | 1 line

Create R-4-2-branch
------------------------------------------------------------------------

I checked this branch out and it already displays the same problem,
the same test in reg-tests-1d.R falls over.  But I am pretty sure that
R-devel (and R-patched) compiled fine on that day. So where was the
change made before the R-4.2-branch was created?

Cheers,
