Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 11:
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) ⊦ ⟪if m < # pebs ∧ ¬ pebs[m].bad then {fail_or_success#(; ; err); if err = ESUCCESS then pebs[m] := mkpeb(emptypeb, 0, pebs[m].bad)} else abort⟫ ⟨aubi_io_sync_erase#(m; apebs; err0)⟩ (abs(pebs, apebs) ∧ err = err0)

Used simplifier rules: mtd_asm_erase#(PNUM; PEBS; ERR) {if PNUM < # PEBS ∧ ¬ PEBS[PNUM].bad then {fail_or_success#(; ; ERR); if ERR = ESUCCESS then PEBS[PNUM] := mkpeb(emptypeb, 0, PEBS[PNUM].bad)} else abort };
