Summary0001806: Error in coq code generated by wp
DescriptionThere is a typing error with some code generated by wp.

For example this script :

_Bool g()
    return 0;

//@ensures x == (!!\result == !!x);
_Bool f(_Bool x)
    return g();

When using prover coq from wp generates :

  forall (f_0 x_0 : Z),
  ((is_uint32 f_0%Z)) ->
  ((is_uint32 x_0%Z)) ->
  ((((Zneq_bool 0 x_0))
    = ((Zeq_bool ((Zneq_bool 0 f_0)) ((Zneq_bool 0 x_0)))))%Z)%Z.

(* auto with zarith. *)

which produce this coq error on "Zneq_bool 0 f_0":

Error: In environment
f_0 : int
x_0 : int
The term "Zneq_bool 0 f_0" has type "bool" while it is expected to have type
Steps To ReproduceJust use the C example with wp/coq as prover (with the gui for example because else wp consider that the script fails and does not print the error)
