Subject: [PATCH] xmalloc: include size in the failure message
Date: Fri, 20 Aug 2010 15:01:12 +0200	[thread overview]
Message-ID: <1282309272-20906-1-git-send-email-Matthieu.Moy@imag.fr> (raw)

Out-of-memory errors can either be actual lack of memory, or bugs (like
code trying to call xmalloc(-1) by mistake). A little more information
may help tracking bugs reported by users.
