The following bug was reported to me by Timo Jolivet last July 2012. It is
still there is sage-5.3:
{{{
sage: s =
WordMorphism({1:[1,2],2:[2,3],3:[4],4:[5],5:[6],6:[7],7:[8],8:[9],9:[10],10:[1]})
sage: (s^7).fixed_points()
[word: 122..., word: 2,3,4,...]
sage: (s^7).reversal().fixed_points()
MemoryError [...]
}}}
