Proof step 33 from proof refine-markbad (previous step)

pebs[m] = mkpeb(buf0, m1, false), apebs[m] = mkpeb(aehdr, avhdr, buf, m0, false), m < # pebs, m < # apebs, abs(pebs, apebs), abs-peb(mkpeb(buf0, m1, false), mkpeb(aehdr, avhdr, buf, m0, false)), mtd-cons(pebs), ubi-io-inv(apebs) ⊦ ⟨abort⟩ (abs(pebs[m, pebs[m].bad:= true], apebs) ∧ ESUCCESS = err), ubi-io-markbad-pre(m, apebs)

Heuristic symbolic execution applied rule abort right

And obtained the following new goals

Proof step 34:
