Proof step 30 from proof test (previous step)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 29:
buf1 = mk(mkarray(2)[0, a][1, b], 2, 1, 1), ar0 = buf1 .data ∧ a1 = c ∧ i0 = 0 ⊦ ⟪if 0 ≤ i0 ∧ i0 < n→i(# ar0) then ar0 := ar0[i→n(i0), a1] else abort⟫ ⟪buf1 := buf1 .data:= ar0 .len:= ((buf1 .data:= ar0) .len + 1)⟫ ⟪a2 := a ; pop#(; buf1, a2) ; assert#(a2 = b) ; pop#(; buf1, a2) ; assert#(a2 = c)⟫ true
