Subject: [PULL 11/25] Fix double free issue in qemu_set_log_filename().
Date: Thu, 19 Dec 2019 10:49:20 +0000	[thread overview]
Message-ID: <20191219104934.866-12-alex.bennee@linaro.org> (raw)
In-Reply-To: <20191219104934.866-1-alex.bennee@linaro.org>

From: Robert Foley <robert.foley@linaro.org>

After freeing the logfilename, we set logfilename to NULL, in case of an
error which returns without setting logfilename.
