N/A

Details

• Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other

Powershell-Core

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

git log --graph -u -L 71,71:FileName

• What did you expect to occur after running these commands?

The standard git log output with information about commits and changes.

• What actually happened instead?

Git prints almost all the output and hangs. Doesn't respond to anything. Only kill from Task manager helps.

• If the problem was occurring with a specific repository, can you provide the
  URL to that repository to help us with testing?

N/A

Additionally I've checked on Ubuntu installed on WSL2 and there is this error in the output:

free(): double free detected in tcache 2
[1]    185698 IOT instruction  git log --graph -u -L 15,15:gulpfile.js > output.txt

It's on different repository.
It started happening on 2.46 so I've upgraded to 2.46.2 and it is still there.

Thanks for this report. Using valgrind, I was able to find a use-after-free in this command. It does look like this change was new in Git 2.46.0. I'll see if I can get this fix into 2.47.0.

[derrickstolee]

The change has been submitted upstream via gitgitgadget#1806.

Thank you @derrickstolee! Let's hope that this gets into Git v2.47.0-rc2, if not, Git for Windows should merge it early, methinks.
