+// Clang headers like to use NDEBUG inside of them to enable/disable debug
+// releated features using "#ifndef NDEBUG" preprocessor blocks to do one thing
+// or another. This is bad because it means that if clang was built in release
+// mode, it assumes that you are building in release mode which is not always
+// the case. You can end up with functions that are defined as empty in header
+// files when NDEBUG is not defined, and this can cause link errors with the
+// clang .a files that you have since you might be missing functions in the .a
+// file. So we have to define NDEBUG when including clang headers to avoid any
+// mismatches. This is covered by rdar://problem/8691220
