Description :
Frama-C fails while typing the given ACSL axiomatic.
Additional Information :
Typing is succesful when axiom "a" is replaced by: @ axiom a: P(aList,Nil);
Steps To Reproduce :
> cat list.i
//@ type List<A> = Nil | Cons(A,List<A>);
/*@ axiomatic L {
@ predicate P<B>(List<B> l1, List<B> l2);
@ logic List<integer> aList{L} ;
@ axiom a: P(Nil, aList);
@ }
@*/
> frama-c list.i
