Hello,
This is my first bug report to Git mailing list so let me know if more information is needed.
Running the following command results in a segmentation fault on macOS arm64
$ git diff --name-only --diff-filter=U —relative
Segmentation fault: 11
I was rebasing while it happened, trying to resolve merge conflicts. This is roughly how the status of the repo looked (I changed the file names, but keep them relative the to output, i.e. ../actual-file.txt I change to ../some-file.txt).
$ git status
interactive rebase in progress; onto a4aabaa
Last command done (1 command done):
pick ad0e02e WIP
No commands remaining.
You are currently rebasing branch 'my_branch' on 'a4aabaa'.
(fix conflicts and then run "git rebase --continue")
(use "git rebase --skip" to skip this patch)
(use "git rebase --abort" to check out the original branch)
Changes to be committed:
(use "git restore --staged <file>..." to unstage)
modified: ../dir1/Makefile
modified: ../dir1/http_spec.yaml
modified: ../dir1/tests/api/file1.rs
modified: file2.proto
Unmerged paths:
(use "git restore --staged <file>..." to unstage)
(use "git add <file>..." to mark resolution)
both modified: ../dir1/build.rs
both modified: ../dir1/tests/data/file3.sql
both modified: file4.go
Running it through lldb doesn’t give too much information, but just in case it helps:
$ lldb -- git diff --name-only --diff-filter=U --relative
(lldb) target create "git"
Current executable set to 'git' (arm64).
(lldb) settings set -- target.run-args "diff" "--name-only" "--diff-filter=U" "--relative"
(lldb) r

I got my Git binary from Homebrew, tried version 2.32.0 and 2.33.0 (currently the latest on Homebrew).
