Subject: [PATCH 1/9] semodule-utils: fix comparison with argc
Date: Sun,  1 Sep 2019 20:06:28 +0200
Message-ID: <20190901180636.31586-2-nicolas.iooss@m4x.org> (raw)
In-Reply-To: <20190901180636.31586-1-nicolas.iooss@m4x.org>

In order for argv[3] to be used, argc needs to be at least 4, not 3.

This bug was found using lgtm.com analyzer:
