According to the thread you linked to Apple has acknowledged this as a bug and it will be fixed in a forthcoming release of the iPhone OS. So it looks like you're out of luck until then. There is no documentation as to what's actually getting leaked, because the leak is inside Apple's code and we (obviously) don't have ready access to Apple's source code.
NSXMLParser will leak if the URL you provided is not valid.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
