Changes (by simonpj):

  * difficulty:  => Unknown


 Thank you.  We know there's a performance bug in the occurrence analyser
 (see #7258), but it's very helpful to have a small case that tickles it.
 Two questions
  * How do you know it's the occurrence analyser at fault?
  * Can you be specific about the changes you made to the test program that
 showed you the memory behaviour was exponential (ugh).
