Proof step 15 from proof crash-neutral-deallocate-gnd (previous step)

ginval1 = ginval, gstore1 = crash(gstore, gstore0, ginval, nx), remove-refsize0(gstore0) = gstore0, elems nx ∩ ginval = ∅, dom gstore0 ∪ elems nx = dom gstore ∪ ginval, inv(gstore \ ginval), inv(gstore0), ri-inj(fi2), ri-inj(fi1), n ∈ gstore, n ∈ gstore0 ⊦ ⟨skip⟩ (ginval1 = ginval ∧ gstore1 = crash(gstore, gstore0, ginval, nx)), dups(nx), n ∈ nx

Heuristic symbolic execution applied rule skip right

And closed the goal!
