Proof step 5 from proof crash-neutral-markbad (previous step)

apebs[n] = mkpeb(aehdr, avhdr, buf, m, false), apebs0 = apebs, n < # apebs, ubi-io-inv(apebs) ⊦ ⟨aubi_io_markbad#(n; apebs; err)⟩ (apebs0 = apebs)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 6:
apebs[n] = mkpeb(aehdr, avhdr, buf, m, false), apebs0 = apebs, n < # apebs, ubi-io-inv(apebs) ⊦ ⟨if ubi-io-markbad-pre(n, apebs) then {fail_or_success#(; ; err); if err = ESUCCESS then apebs[n].bad := true} else abort⟩ (apebs0 = apebs)
