Proof step 34 from proof test (previous step)

buf = mk(mkarray(2)[0, a][1, b], 2, 1, 1) ⊦ ⟪let j = (buf .first + buf .len) % buf .size in { buf0 := buf ; put#(j, c; buf0 .data) }⟫ ⟪buf0 := buf0 .len:= (buf0 .len + 1)⟫ ⟪a2 := a ; pop#(; buf0, a2) ; assert#(a2 = b) ; pop#(; buf0, a2) ; assert#(a2 = c)⟫ true

Heuristic symbolic execution applied rule vardecls right

And obtained the following new goals

Proof step 33:
