Undefinedly, most usually explodedly.
For libraries that have sanity checks on the comparator, hard asserts. For the rest (or NDEBUG), amusing loss of elements and general malfunction.
Then it seems reasonable to me for ICL to also opt not to support NaN's in favor of a simpler implementation, better performance, etc. - Jeff
