From: Paul Eggert <eggert <at> cs.ucla.edu> To: 79018 <at> debbugs.gnu.org Subject: bug#79018: vc-test-cvs06-version-diff failure on GNU/Linux with current master Date: Mon, 14 Jul 2025 08:46:53 -0700
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
