I havn't looked at it in very detail, but it is most probably the 
assigns clause that's causing trouble here. Comprehension (i.e. the 
possibility of considering the set of all q->hd such that reachable(p,q) 
is supported by the front-end, but not by any plug-in I know of. I'm 
afraid Frama-C Nitrogen won't help in this particular case.

There have been few attempts to study  such structures so far, but I 
have to admit that it is not the main topic of most usages of Frama-C.

Best regards,
