NaN (specifically of the IEEE754 variety) is supposed to compare
non-equal even when compared to itself.  I recognize that eql is used in
the above, but that would probably still create two LISP objects that
happen to have the same value, but the established FP math says these
two values should not compare equal anyway.  If you stray from that
convention there should be a really good reason for that and it needs to
be prominently documented.
