I'm a little confused.
So am I :-) Looks like I modified `foldr1`, while the test case still tested `maximumBy` from `Data.OldList` which still goes via `foldl1`, and thus was always ok for the test case. The `maximumBy` that one gets from `Data.List` is the one from `Foldable`, which goes via `foldr1`, so it stills blows the stack. But I’m not sure what to do here. We might be able to special-case `Int` and `Integer`, but that does not seem to be a good solution... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10830#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
