Proof step 7 from proof inv-destroy-buf (previous step)

# buf = EB_PAGE_SIZE, ¬ rofs, bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m, m0), avol[bleb.leb], rofs) ⊦ ⟪bleb := nobuffer; err := ESUCCESS⟫ (bleb ≠ nobuffer → bleb.leb < # avol ∧ wbuf-cons(mkwbuf(buf, m, m0), avol[bleb.leb], rofs))

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
