purify result

I run the version xerces C++ version 1.7.0 under purify, and I got this result
when I am parsing one of my xml file( see the below text).
I am using DOMParser.  Does anyone already has a fix for this?  Is this a
known problem??  I am on a unix box, solaris.

Thanks!!!

RE: purify result

Posted by Dean Roddey <dr...@charmedquark.com>.
That's most likely a bogus error. Tools like Purify cannot figure out
that this is a purposeful return of an allocated object. They cannot see
a delete in the same block so they report it as a leak. Its only a real
leak if the caller of this method doesn't delete it.
