This test has been failing for some time and I am now getting around to 
reporting it. I see it on Ubuntu 25.04 x86-64, on a zfs file system. I 
also see it on Fedora 42 x86-64, on an ext4 file system.

To reproduce, build Emacs from master and run "make check". Here is the 
shell transcript of a run of the individual test case:

$ cd test
$ make check LOGFILES=lisp/vc/vc-tests/vc-tests.log
