This is bad because it means that if clang was built in release 21// mode, it assumes that you are building in release mode which is not always 22// the case. You can end up with functions that are defined as empty in header 23// files when NDEBUG is not defined, and this can cause link errors with the 24// clang .a files that you have since you might be missing functions in the .a 25// file. So we have to define NDEBUG when including clang headers to avoid any 26// mismatches.
