You may want to download, install and use the CLANG checker tool to understand why your code is leaking memory. This tool (which is already built for Leopard 10.5.x) may sometimes fail to provide the correct answer, but in my personal experience it never failed. I highly recommend it as one of your daily development tools.

You can download it from

http://clang.llvm.org/StaticAnalysis.html

Usage it really simple. Take a look at

http://clang.llvm.org/StaticAnalysisUsage.html#BasicUsage

In practice, you simply build your Xcode project using the command

scan-build -k -V xcodebuild

then, you inspect the resulting output HTML files using the command that will appears as output in your terminal window. These files will give you a detailed explanation of why something is wrong in your code (not just memory leaks).

Kind regards
