Xcode 7: crash when stopping breakpoint

Question

I have a very nasty problem! Xcode 7 fires at almost every breakpoint when it tries to symbolize.

I have done several things, including uninstalling Xcode and reinstalling ...

I also had the same issue on previous Xcode 6.X

Any clue? I am wondering if I need to reinstall Mac OS from scratch ...

I solved the problem by changing the optimization level in the build settings, make sure the Debug configuration is set to None, and make sure your RUN scheme uses the Debug configuration.
