Proof step 4 from proof icrash-remove-refsize0-prefix (previous step)

istore0 = remove-refsize0(istore0), istore0 ⊑ istore ⊦ dom istore0 ⊆ dom remove-refsize0(crash(istore, istore0)) ∧ (∀ n. n ∈ istore0 ∧ n ∈ remove-refsize0(crash(istore, istore0)) → istore0[n].indlist ⊑ remove-refsize0(crash(istore, istore0))[n].indlist ∧ istore0[n].ladrlist ⊑ remove-refsize0(crash(istore, istore0))[n].ladrlist ∧ # istore0[n].indlist = # istore0[n].ladrlist ∧ # remove-refsize0(crash(istore, istore0))[n].indlist = # remove-refsize0(crash(istore, istore0))[n].ladrlist)

And obtained the following new goals

Proof step 5:
istore0 = remove-refsize0(istore0), n ∈ istore0, n ∈ istore, istore0 ⊑ istore ⊦ crash(istore, istore0)[n].ref-size = 0, istore0[n].indlist ⊑ remove-refsize0(crash(istore, istore0))[n].indlist ∧ istore0[n].ladrlist ⊑ remove-refsize0(crash(istore, istore0))[n].ladrlist ∧ # istore0[n].indlist = # istore0[n].ladrlist ∧ # remove-refsize0(crash(istore, istore0))[n].indlist = # remove-refsize0(crash(istore, istore0))[n].ladrlist
