This is bad because it means that if clang was built in release 19 // mode, it assumes that you are building in release mode which is not always 20 // the case. You can end up with functions that are defined as empty in header 21 // files when NDEBUG is not defined, and this can cause link errors with the 22 // clang .a files that you have since you might be missing functions in the .a 23 // file. So we have to define NDEBUG when including clang headers to avoid any 24 // mismatches.
