Proof step 10 from proof inv-markbad (previous step)

pebs[m] = mkpeb(buf, m0, false), m < # pebs, mtd-cons(pebs), ⌊err0⌋ ∨ err0 = ESUCCESS ⊦ ⟪err := err0; if err = ESUCCESS then pebs[m].bad := true⟫ mtd-cons(pebs)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
