 The program oneRound.hs at ( http://www.lama.univ-
 savoie.fr/~meunier/f48426a8666aebd8c191f090ccfcf66ceb8ca839/ : there are
 two files)

 produces a bus error, depending on whether the strictness annotations on
 line 70 of Elementary.hs are present or not.

 By the way, ghc is not able to figure out that this subfunction should be
 strict, and this is the inner loop of my program.
