apebs[n6] = mkpeb(aehdr, avhdr, buf1, m, false), buf0 = buf, n = n3, n0 = n4, n1 = n5, n2 = n6, n6 < # apebs, ubi-io-inv(apebs), n4 + n3 ≤ # buf, n5 + n3 ≤ LEB_SIZE ⊦ ⟨abort⟩ true, ubi-io-read-data-pre(n2, n1, n0, n, buf0, apebs)

Heuristic symbolic execution applied rule abort right

And obtained the following new goals
