Hi, for the following instance,

(set-logic QF_UFBV)
(set-option :smt.clause_proof true)
(declare-const v0 Bool)
(declare-const v3 Bool)
(declare-const v4 Bool)
(declare-const v5 Bool)
(declare-const bv_22-0 (_ BitVec 22))
(assert (and v0 (xor v0 v3 v0 v4 v3 v5)))
(push 1)
(assert (distinct (bvsgt bv_22-0 (bvnot bv_22-0)) (xor v0 v3 v0 v4 v3 v5)))
(pop 1)
(check-sat-using smt)

z3 (commit 9be7bda) throws ast_manager LEAK.
