Sigh. My system insists on rewriting outgoing mail headers, and
ghc-users refuses non-subscribers to post there. I'm too tired to fight
this at the moment, so I'll send it here in the hope that it will be
picked up by the right adressee.

Subject: Bug in Data.IntSet?

AFAICT, there is a bug in Data.IntSet.split
Here's an excerpt from GHCi:
*Main> let m=482 in Data.IntSet.split (16*m) $ Data.IntSet.fromList (List.map
(m*) [17,18,19,30,40])
({8194,8676,9158},{14460,19280})
*Main> let m=481 in Data.IntSet.split (16*m) $ Data.IntSet.fromList (List.map
(m*) [17,18,19,30,40])
({},{8177,8658,9139,14430,19240})
*Main> let m=481 in Data.Set.split (16*m) $ Data.Set.fromList (List.map (m*)
[17,18,19,30,40])
({},{8177,8658,9139,14430,19240})
*Main> let m=482 in Data.Set.split (16*m) $ Data.Set.fromList (List.map (m*)
[17,18,19,30,40])
({},{8194,8676,9158,14460,19280})
*Main> let m=482 in Data.Set.split (16*m) $ Data.Set.fromList (List.map (m*)
[17,18,19,30,40]::[Int])
({},{8194,8676,9158,14460,19280})
