I have a app that need to use libbz, and when use Xcode to build and launch, it will crash and the console will print: dyld log And I found when I set the compiler settings for debug: Optimization Level -> Fastest, smallest[-Os] Link Time Optimization -> No the crash does not appear. but for debug, I think the the right compiler settings is: Optimization Level -> None[-O0] Link Time Optimization -> Increment why this happened and what can I do to fix it?

When debug app, it will crash when app launch, and print below info: libbz2.1.0.dylib is a system library, and how we can resolve this problem?
