Proof step 6 from proof crash-neutral-read-gnd (previous step)

Heuristic symbolic execution applied rule if positive right

And obtained the following new goals

Proof step 7:
syn ↔ true, adr = @(m, m0, m1), fi = fi1, fi0 = fi2, ginval = ginval2, ginval0 = ginval1, gstore = gstore1, gstore0 = gstore2, maxino = maxino0, remove-refsize0(gstore1) = gstore1, elems nx ∩ ginval1 = ∅, dom gstore1 ∪ elems nx = dom gstore2 ∪ ginval1, inv(gstore2 \ ginval1), inv(gstore1), ri-inj(fi2), ri-inj(fi1), @(m, m0, m1) ∈ gstore2 ⊦ ⟨fail_or_success#(; ; err); if err = ESUCCESS then gnd := gstore0[adr] else gnd := ?⟩ true, dups(nx), m ∈ ginval1
