Subject: [PATCH 1/3] merge-recursive: fix memory leak
Date: Mon, 28 Aug 2017 14:28:27 -0600 [thread overview]
Message-ID: <20170828202829.3056-2-kewillf@microsoft.com> (raw)
In-Reply-To: <20170828202829.3056-1-kewillf@microsoft.com>
In merge_trees if process_renames or process_entry returns less
than zero, the method will just return and not free re_merge,
re_head, or entries.
This change cleans up the allocated variables before returning
to the caller.
