memory management problems in xcode 4

As the title states, is anyone else facing memory management problems when using Xcode 4? my projects run perfectly when running with Xcode 3 but shows many warnings and crashes due to memory mismanagement... I would also like to know if the latest Xcode 开发者_高级运维update added more memory management rules...

Memory management problems is IDE independent, so the answer is "No". If you have problems in xcode3, they will be there if you edit your code in xcode4 or notepad too.

Maybe the real problem is something else?
