Subject: [PATCH 1/2] nfs4-acl-tools: Fix segfault if format of the input file is incorrect
Date: Thu, 21 Jul 2011 13:35:06 -0700	[thread overview]
Message-ID: <1311280507-28957-1-git-send-email-malahal@us.ibm.com> (raw)

The sizeof operator, when applied to a parameter declared to have array,
yields the size of the adjusted (pointer) type, even if the parameter
declaration specifies a length.
