Subject: [PATCH v2 4/6] clone: fix a memory leak of the "git_dir" variable
Date: Fri, 22 Oct 2021 10:55:42 +0200	[thread overview]
Message-ID: <patch-v2-4.6-0d0e6359cf4-20211022T085306Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v2-0.6-00000000000-20211022T085306Z-avarab@gmail.com>

At this point in cmd_clone the "git_dir" is always either an
xstrdup()'d string, or something we got from mkpathdup(). Let's free()
it before we clobber it.
