Hmmm.  The implement exceptions pass (before closure conversion)
introduces exceptions to implement generativity.  The closure
converter doesn't introduce unit refs, as far as I can remember.  It
does, however, introduce a unit whenever there is an empty closure
record.  Could you send the input and output?
