Hi, for the following formula

(set-logic QF_NIA)
(declare-fun i2 () Int)
(assert (= true true true true (distinct 0 (abs i2) 3337)))
(check-sat)

yices_smt2 --incremental yields

(error "mcsat: unsupported theory")

After replacing abs i2 with i2, yices can work well.
Is this because of a missing support of the abs function?
