Subject: [PATCH v1 5/5] Fix double free issue in qemu_set_log_filename().
Date: Tue, 12 Nov 2019 10:01:05 -0500 [thread overview]
Message-ID: <20191112150105.2498-6-robert.foley@linaro.org> (raw)
In-Reply-To: <20191112150105.2498-1-robert.foley@linaro.org>
After freeing the logfilename, we set logfilename to NULL, in case of an
error which returns without setting logfilename.
