Bug with `git branch HEAD` in a 'detached HEAD' state

Benoît Legat· Aug 15, 2013, 20:50 UTC · lore

Hello everyone,

I think I have just found a bug in Git which basically occurs when I run `git log HEAD` in a detached HEAD state. To reproduce it, just run $ git init ... $ touch tmp ... $ git add tmp $ git commit -m "tmp" ... $ git checkout <commit_sha> ... $ git branch HEAD Segmentation fault (core dumped)

My version of git is the following $ git --version git version 1.8.1.2

If that helps (and even if it doesn't actually), I'm running ubuntu 13.04 64-bit.

This should be fixed by 8efb8899cfe866dddb3659b9e0a94232161db65e (2013-02-23, branch: segfault fixes and validation)

I could reproduce with 1.8.1.2, but not on current master branch. If this annoys you too much, please update your git version. ;)
