Hi there,
I'm experiencing some troubles with Why3 and Z3.
I found a small reproducer for my issue:
theory Test
use import int.Int
type myRecord = { value : int }
axiom value_axiom : forall i1 : myRecord. i1.value >= 1
goal test: forall i: myRecord.
1 < i.value
end
If you
Hi Arnaud,

type holding that value. So, your value_axiom axiom states,
essentially, that all integers are greater than one, which is false.
Having a false axiom makes every proof obligation trivially provable,
just as your examp

Hi Arnaud,
That's a usual problem when y

Indeed you are right I'm trying to translate some data structure and I
have to deal with such problems.
I will have a look at these and thanks for the pointers.
