Xcode 4.6.1 debugger local variables not available

I recently upgraded Xcode 4.6 to 4.6.1, and I notice the following abnormal behaviour:

  1. Sometimes, Local Variables are not available upon a breakpoint

  2. Upon Step Into and Step Over when being suspended over a breakpoint, the editor highlights the incorrect line the code.

The LLVM 4.2 Compiler - COde Generation / Optimization level is set to None for Debug. I have tried cleaning the project, the simulator, etc. No luck.

Any clues?

    Attached is where I had made a mistake:
