Xcode 4.6 Strange issues with Debugger."po" command does not work

Question

I just recently upgraded to xcode 4.6 and strange things are happening to the debugger. "po" command ceases to work some times. Also step by step debugging sometimes does not work. Is anybody else having the same issues

Answer 1

I have found the issue with this. I checked the Optimization Level for your Apple LLVM Compiler code compilation in target settings, changed it to None and now the debugging works as it should
