Subject: [PATCH v2 1/3] setup: free old value before setting `work_tree`
Date: Mon, 14 Jan 2019 19:34:55 +0100
Message-ID: <8585c0bfdc071f17e75346b801a16580d360c18a.1547488709.git.martin.agren@gmail.com> (raw)
In-Reply-To: <cover.1547488709.git.martin.agren@gmail.com>

Before assigning to `data->work_tree` in `read_worktree_config()`, free
any value we might already have picked up, so that we do not leak it.
