And obtained the following new goals

Proof step 88:
st[r0 -- sks] .refval = r0, (st[r0 -- i ', refval(r1)][r0 -- (sks + i ' ' + sks1)]) = refval(r1), st[r0 -- _type] .type = mkarraytype(ty), 0 < st[r0 -- _length] .intval, 0 ≤ i, i < st[r0 -- _length] .intval, fits(r0, sks + i ' ' + sks1, st[r0 -- i ', refval(r1)]), validref(str, r1, ty, st), disjoint(str, r0 ' + r1 ', st) ⊦ r1 = jvmref, r0 = r1, r0 = jvmref, sks + i ' ' + sks1 = i ' ', hasSharing(r0, st), hasSharing(r1, st), junkref(str, r0, st), ∃ sks2. ¬ (sks2 + i ' ' ⊑ sks → st[r0 -- sks2] .refval ≠ r0)
