Z3 (master 6384080) reports sat instead of unsat for the following formula:

(declare-const A0 (Array Int Int))
(declare-const A1 (Array Int Int))
(assert (= A0 ((as const (Array Int Int)) 0)))
(assert (= A1 ((as const (Array Int Int)) 1)))
(assert (= (store A0 2 3) (store A1 2 3)))
(check-sat)

The model Z3 reports is:

sat
(model 
  (define-fun A0 () (Array Int Int)
    ((as const (Array Int Int)) 0))
  (define-fun A1 () (Array Int Int)
    ((as const (Array Int Int)) 1))
)

Does Z3 fully support equalities over constant arrays?
