Comment (by knarf):

 Why is MoLDebug used here? If this triggers, the code aborts anyway. I
 don't see harm in outputting too much information in that case.
 Also, please make the message a bit more "official". "Arg" is cute and
 all, but maybe you could think of something better? :)

 Could CCTK_ERROR be used instead of CCTK_WARN(0, ?
