Plot of points from a failing example. Generated using:

writeFile "brokenPoints.csv"
  $ concat 
  $ [concat $ map (\(a,b) -> printf "%f %f %d\n" a b n :: String) (fun f)
        | (fun, n)  <- [id, gscan', gscan' . gscan' ] `zip` [ 0 :: Int .. ] ]

And plotted with R

xyplot(V1 ~ V2 | factor(V3),
        read.table('brokenPoints.csv', header=F),
        layout=c(NA,1), xlab='x', ylab='y', type='b' )
