As of now Clang complier is not available for Xcode 4 (available for Xcode 3.2), it has the default LLVM GCC 4.2 complier. We may get that in future release, to know the error code message better.

Additional:

You must build your code using this Analyzer to fix the potential memory leaks and other issues.
