On Fedora 41 x86-64 with the current Emacs master (commit
4936a8d5acbfee2dee6d903400eba48cb2e3a6a7) I occasionally see failures of
the vc-git-test-dir-branch-headers test. Usually it works. Here are the
two failures I've seen.
The first was with a "make -j5 check" so it may have been a collision
with some other test:

The second failure was with "make lisp/vc/vc-git-tests" in the test
directory. I repeatedly ran that test, and it failed on the 20th
execution as follows:
