| Summary | 0001806: Error in coq code generated by wp |
| Description | There 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 :
Goal
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.
Proof.
(* auto with zarith. *)
Qed.
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
"int". |
| Steps To Reproduce | Just 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) |
