is now closed.

-// Clang headers like to use NDEBUG inside of them to enable/disable debug
-// related 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
