Subject: [PATCH v3 03/21] trace-cmd library: Fix version string memory leak
Date: Tue, 14 Sep 2021 16:12:14 +0300 [thread overview]
Message-ID: <20210914131232.3964615-4-tz.stoyanov@gmail.com> (raw)
In-Reply-To: <20210914131232.3964615-1-tz.stoyanov@gmail.com>
The version string is allocated when a VERSION option is processed, but
is never freed. Free it on input handler close.
