Proof step 3 from proof crash-neutral-deallocate-gnd (previous step)

ginval0 = ginval, gstore1 = crash(gstore, gstore0, ginval, nx), remove-refsize0(gstore0) = gstore0, elems nx ∩ ginval = ∅, dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore \ ginval), inv(gstore0), ri-inj(fi), ri-inj(fi0), n ∈ gstore, n ∈ gstore0, ¬ dups(nx), ¬ n ∈ nx ⊦ ⟨index_deallocate_gnd#(n, fi, fi0, gstore0, nx, maxino0, ginval2, true; ginval, gstore; err)⟩ (ginval0 = ginval ∧ gstore1 = crash(gstore, gstore0, ginval, nx))

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 4:
syn ↔ true, fi = fi1, fi0 = fi2, ginval0 = ginval2, ginval1 = ginval, gstore1 = crash(gstore, gstore0, ginval, nx), maxino = maxino0, remove-refsize0(gstore0) = gstore0, elems nx ∩ ginval = ∅, dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore0), inv(gstore \ ginval), ri-inj(fi1), ri-inj(fi2), n ∈ gstore0, n ∈ gstore ⊦ ⟨if syn ∧ n ∈ gstore ∧ ¬ n ∈ nx then {fail_or_success#(; ; err); if err = ESUCCESS then gstore := gstore -- n, ginval := ginval ++ n} else abort⟩ (ginval1 = ginval ∧ gstore1 = crash(gstore, gstore0, ginval, nx)), dups(nx), n ∈ nx
