  [t9402-git-cvsserver-refs.sh                      (Wstat: 256 (exited 1) Tests: 37 Failed: 4)
  Failed tests:  30-32, 34
  Non-zero exit status: 1]: [This message shows which tests have failed]
=============
['cvs.log' is not empty, it contains:
++ cat cvs.log
Possible precedence problem between ! and pattern match (m//) at /builddir/build/BUILD/git-2.49.0-build/git-2.49.0/git-cvsserver line 5015.]: [This code shows why the test has failed]

Issue: The build has failed because of Perl warning message has populated cvs.log during the tests. The tests doesn't expect this message and fail instead.
Resolution: Work with upstream code to suppress this Perl warning. The code that produces this warning is in file git-cvsserver on line 5015
