And obtained the following new goals

Proof step 21:
⊦ ¬ is_referencevalue(st[r -- sks]) ∧ ¬ junkref(str, r, st) → ¬ fits(r, sks + sk ', st)
Proof step 32:
st[r -- sks1] = refval(r1), st[r0 -- sks] = refval(r2), fits(r, sks1 + mkfs(class, ty, fieldvar) ' ', st), fits(r0, sks + i ' ', st), i ' ∈ sks1 ⊦ sks1 = [], (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]), sks = [], is_referencevalue(st[r2 -- i ']), is_reftype(ty), is_referencevalue(val0), is_referencevalue(val), mkfs(class, ty, fieldvar) ' ∈ sks, junkref(str, r0, st), junkref(str, r, st), ¬ junkref(str, r2, st) ∧ fits(r, sks1, st)
