Proof step 40:
st[r0 -- sks] = refval(r2), st[r -- sks1] = refval(r1), fits(r0, sks + i ' ', st), fits(r, sks1 + mkfs(class, ty, fieldvar) ' ', st) ⊦ sks = [], (st[r2 -- i ', val0][r1 -- mkfs(class, ty, fieldvar) ', val]) = (st[r2 -- i ', val0][(st[r2 -- i ', val0][r -- sks1]) .refval -- mkfs(class, ty, fieldvar) ', val]), mkfs(class, ty, fieldvar) ' ∈ sks, is_referencevalue(val), is_referencevalue(val0), is_reftype(ty), is_referencevalue(st[r0 -- (sks + i ' ')]), junkref(str, r, st), junkref(str, r0, st)
