  The following constraint associated with `incr` is false:
	  (((1 : Level) ∨ (prom_[9:34]0 * ((1 : Level) ∨ (1 : Level)))) ∨ ((Private ∨ (l * (1 : Level))) ∨ (1 : Level)) ≤ Dunno) ∧ (((1 : Level) ∨ (prom_[9:34]0 * ((1 : Level) ∨ (1 : Level)))) ∨ ((Private ∨ (l * (1 : Level))) ∨ (1 : Level)) ≤ (1 : Level)) ∧ (prom_[9:34]0 * (1 : Level) ≤ l) ∧ ((prom_[9:34]0 * (1 : Level)) + (l * (1 : Level)) ≤ l) ∧ (l ≤ prom_[9:34]0) ∧ (prom_[9:34]0 ≤ l)

Counter-example:
  l = Public :: Level
