Proof step 19:
⊦ ¬ is_referencevalue(st[r -- sks]) ∧ ¬ junkref(str, r, st) → ¬ fits(r, sks + sk ', st)
Proof step 36:
st[r -- sks1] = refval(r1), st[r0 -- sks] = refval(r2), fits(r, sks1 + i ' ', st), fits(r0, sks + mkfs(class, ty, fieldvar) ' ', st) ⊦ (st[r1 -- i ', val][(st[r1 -- i ', val][r0 -- sks]) .refval -- mkfs(class, ty, fieldvar) ', val0]) = (st[r1 -- i ', val][r2 -- mkfs(class, ty, fieldvar) ', val0]), sks1 = [], junkref(str, r0, st), junkref(str, r, st), is_reftype(ty), is_referencevalue(st[r -- (sks1 + i ' ')]), is_referencevalue(val0), is_referencevalue(val), mkfs(class, ty, fieldvar) ' ∈ sks1, sks ≠ [] ∧ ¬ junkref(str, r1, st) ∧ fits(r0, sks, st) ∧ ¬ is_referencevalue(st[r1 -- i '])
