Proof step 12 from proof crash-neutral-read (previous step)

m2 < # avols[v], ebm-cons(avols), ebm-cons(avols0), v ∈ avols, m1 + n ≤ LEB_SIZE, n0 + n ≤ # buf, avols ⊆ avols0 ⊦ ⟨choose buf1 with # buf1 = # buf ∧ range=(buf1, 0, buf, 0, n0) ∧ range=(buf1, n0 + n, buf, n0 + n, # buf - n0 + n) in buf := buf1⟩ true

Heuristic symbolic execution applied rule choose right

And obtained the following new goals
