Subject: [Qemu-devel] [PATCH 1/3] qdist: fix memory leak during binning
Date: Mon, 25 Jul 2016 11:03:43 -0400	[thread overview]
Message-ID: <1469459025-23606-2-git-send-email-cota@braap.org> (raw)
In-Reply-To: <1469459025-23606-1-git-send-email-cota@braap.org>

In qdist_bin__internal(), to->entries is initialized to a 1-element array,
which we then leak when n == from->n. Fix it.
