Subject: [Qemu-devel] [PATCH 4/4] vl.c: fix memory leak
Date: Fri, 10 Jul 2015 08:51:30 +0800	[thread overview]
Message-ID: <1436489490-236-5-git-send-email-arei.gonglei@huawei.com> (raw)
In-Reply-To: <1436489490-236-1-git-send-email-arei.gonglei@huawei.com>

From: Gonglei <arei.gonglei@huawei.com>

Failing to save or free storage allocated
by "g_strdup(cmd)" leaks it. Let's use a
variable to storage it.
