Proof step 40 from proof refine-isbad (previous step)

m < # apebs, abs(pebs, apebs), mtd-cons(pebs), ubi-io-inv(apebs), ⌊err1⌋ ⊦ ⟨err := err1; if err = ESUCCESS then isbad := apebs[m].bad else isbad := ?⟩ ((isbad1 ↔ isbad) ∧ err1 = err)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
