From fed2ef094f85b3063b9fc9e6d9c8462e60a9ad3a Mon Sep 17 00:00:00 2001
From: Pedro Vicente Nunes <pvn@hdfgroup.org>
Date: Fri, 25 Mar 2005 10:07:06 -0500
Subject: [svn-r10416] Purpose: bug fix

Description:
when exiting due to a error condition on the goto out instruction there was an attempt to call
H5Dvlen_reclaim without checking if buf was null

Solution:
checket it

Platforms tested:
linux
solaris
IRIX64
AIX
