Yes, this feature is turned off in C++. From Sema::LookupName:

         // In C++, we don't have any predefined library functions like
         // 'malloc'. Instead, we'll just error.
         if (getLangOptions().CPlusPlus &&
             Context.BuiltinInfo.isPredefinedLibFunction(BuiltinID))
           return LookupResult::CreateLookupResult(Context, 0);

I'll add a test.
