And obtained the following new goals

Proof step 4:
adr = adr1, adr0 = adr2, ginval = ginval1, ginval0 = ginval2, gstore = gstore1, gstore0 = gstore2, istore = istore1, istore0 = istore2, remove-refsize0(istore1) = istore1, remove-refsize0(gstore1) = gstore1, elems nx ∩ ginval2 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval2, inv(istore1), inv(istore2), inv(gstore1), inv(gstore2 \ ginval2), adr2 ∈ istore2, istore1 ⊑ istore2, pstate = unbuffered → syn, pstate.index? → pstate.lnum ∈ istore2, pstate.journal? → nx ≠ [] ∧ pstate.lnum = nx.last ∧ pstate.lnum ∈ gstore2 ⊦ ⟪if adr0 ∈ istore0 then {fail_or_success#(; ; err); if err = ESUCCESS then ind := istore0[adr0] else ind := ?} else abort⟫ true, dups(nx)
