make test failed about [email protected] on ubuntu_aarch64

hello,I meet a problem:make test failed about [email protected] on ubuntu_aarch64

Steps to reproduce the issue

root@ubuntu:~/tig-2.5.6# make test
...
      TEST  test/main/all-arg-test
      TEST  test/main/author-name-change-test
fatal: unsafe repository ('/root/tig-2.5.6/test/tmp/main/author-name-change-test/work-dir' is owned by someone else)
To add an exception for this directory, call:

        git config --global --add safe.directory /root/tig-2.5.6/test/tmp/main/author-name-change-test/work-dir
            | No test results found
Makefile:278: recipe for target 'test/main/author-name-change-test' failed
make: *** [test/main/author-name-change-test] Error 128

Can you tell me why this problem arises?

This is due to CVE-2022-24765 mitigation in Git v2.35.2. When you run the test suite as root, the repo is untarred with the original UID and git's safeguard is blocking the test. Easily fixed.
