Proof step 18 from proof id-idx-lpt-free-unref (previous step)

# lpt1 = # lpt0, lpt1[n] = mklp(m, m0, LP_FREE, m1), n < # lpt0, ∀ n. n < # lpt0 → lpt0[n].ref-size = lpt1[n].ref-size ∧ lpt0[n].size = lpt1[n].size ∧ lpt0[n].flags = lpt1[n].flags, ∀ n. n < # lpt0 ∧ lpt0[n].flags = LP_FREE → lpt0[n].ref-size = 0 ⊦ m = 0

User applied rule all left

And obtained the following new goals

Proof step 19:
# lpt1 = # lpt0, lpt1[n] = mklp(m, m0, LP_FREE, m1), n < # lpt0, n < # lpt0 → lpt0[n].ref-size = lpt1[n].ref-size ∧ lpt0[n].size = lpt1[n].size ∧ lpt0[n].flags = lpt1[n].flags, ∀ n. n < # lpt0 ∧ lpt0[n].flags = LP_FREE → lpt0[n].ref-size = 0 ⊦ m = 0
