I get a different error running the example code you included. However, 
the problem is almost certainly because you are using ic's search/6 
predicate with real intervals. As the document states, search/6 should 
be used with finite domain variables only -- the specific error you show 
is almost certainly because the code in search/6 is expecting your real 
interval variables to be finite domain. It probably should catch such 
errors in a more informative way.
