The following example in the web interface of poussin
(versions 1 and 2 http://web.yl.is.s.u-tokyo.ac.jp/~nicolas/poussin/index.html
and
http://web.yl.is.s.u-tokyo.ac.jp/~nicolas/poussin2/index.html)
is wrongly rejected:

Inductive nat : type :=
| O : nat
| S : V (x: nat). nat.

Recursive f (x:nat) [0] : nat := match x with | O | \ (xx:nat) . f O.
