Subject: Segfault in git when using git logs
Date: Mon, 2 Nov 2020 15:59:59 +0200	[thread overview]
Message-ID: <CAMsWJsyPVQWV++gc2YJriEOEWBELa_xj2G0NWFMSgNYt47swiQ@mail.gmail.com> (raw)

Hi,

My code editor kept crashing repeatedly and when poked in syslogs, I
found that git was segfaulting. I can repro this easily (steps below).
This is the first time I'm reporting a bug here so I apologize if I've
gotten anything wrong.

Below is the output from git bugreport

Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

Try to find commit logs for a file. I can repro this on a new repo as
well as an existing repo.

Simple repro steps

        mkdir git_segfault_test && cd git_segfault_test && echo
"Hello" > hello.log
        git init && git add hello.log && git commit -m "init commit"

Now, use git log to show commit logs using command

        git log  --follow -L 1,1:hello.log -- hello.log

What did you expect to happen? (Expected behavior)
Git should not segfault

What happened instead? (Actual behavior)
Git segfaulted

What's different between what you expected and what actually happened?

Anything else you want to add:
Note that I am not calling the git log commands directly, my editor VS
Code was repeatedly crashing and I searched in syslog and found this
error.

Please review the rest of the bug report below.
