Hi, this bugreport is about a SEGFAULT on git binary when running in
this repository (for example, as it also segfault on other private
repositories): https://framagit.org/groolot-association/osc_looper.git


What did you do before the bug happened? (Steps to reproduce your
issue) I just wanted to list branches, and so playing with 'git
show-branch --current --reflog=3' in the repository
https://framagit.org/groolot-association/osc_looper.git

What did you expect to happen? (Expected behavior)
Not to segfault

What happened instead? (Actual behavior)
This command fails with a SEGFAULT on version 2.35.1, 2.20.1 and 2.17.1
It also SEGFAULT on branch 'next' of github git repository.

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

Anything else you want to add:
Segfaut happened when '--current' AND '--reflog=3' are provided together

Please review the rest of the bug report below.
