From 4f331872bc783445c709e5fe4846b8687e274953 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Wed, 18 Jul 2012 04:54:31 +0930 Subject: talloc: don't allow a talloc_pool inside a talloc_pool. We explicitly call free() on a pool which falls to zero, assuming it's not inside another pool (we crash). Check on creation and explicitly document this case.
