Proof step 32:
(st[r0 -- i ', val][r -- i0 ']) = refval(r2), 0 ≤ i0, 0 < st[r -- _length] .intval, is_array(str, r, st[r0 -- i ', val]), st[r -- _type] .type ≤ ty, is_array(str, r, st), i0 < st[r -- _length] .intval, is_referencevalue(st[r0 -- i ', val][r -- i0 ']), junkrefs(str, r2 ' + refs, st[r -- _type] .type .type, st[r0 -- i ', val]), ∀ str0, ty0, st0, r1, i1, val0. junkrefs(str0, r2 ' + refs, ty0, st0[r1 -- i1 ', val0]) → junkrefs(str0, r2 ' + refs, ty0, st0) ∨ is_array(str0, r1, st0) ⊦ r = jvmref, is_array(str, r0, st), junkrefs(str, r ' + r2 ' + refs, ty, st)
