Similar issue to and CLJ-1253, with the same root cause as described for CLJ-1225. Ticket filed separately from for long division / because the desired fix may be quite different in this case.
Rich Hickey stated in a comment on that this case should throw an exception.
Question: For inc (which throws when given input Long/MAX_VALUE) there is an auto-promoting inc' and an unchecked-inc. quot now throws an exception in this case. Should there be an auto-promoting quot' and an unchecked-quot?
