Several tests in test/lisp/emacs-lisp/package-tests.el have been failing
on my end since the following commit:

  Merge branch 'feature/package+vc'
  5fa2f11679 2022-11-04 18:57:45 +0100
  https://git.sv.gnu.org/cgit/emacs.git/commit/?id=5fa2f11679

The failures do not happen on the merge commit's first parent:

  * lisp/simple.el (function-documentation): Fix bug#59014
  616aa23d8a 2022-11-04 11:59:51 -0400
  https://git.sv.gnu.org/cgit/emacs.git/commit/?id=616aa23d8a

I attach a log of building Emacs followed by two invocations of
'make test/package-tests', the first using the suite's .el file and the
second using the .elc.  The failures are the same either way.  Each run
is preceded by "echo '>>> TEST EL[C]'" for easier locating in the log.

Let me know if you'd like me to run anything else on my end.

Thanks,
