Subject: [PATCH] get_local_heads(): do not return random pointer if there is no head

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Fri, 17 Apr 2009 08:16:23 +1000

it's silly to do this:

mkdir foo && cd foo && git init && git push somewhere.git

but segfault should not happen even in that case.
