Assertion error at SimpleAPI.scala:4231

[rainoftime]

Hi, for the following formula
ostrich 2b3eb9b

(set-logic LRA)

(declare-fun x () Real)
(assert (forall ((y Real)) (=> (> y 0) (>= y x))))
(check-sat)
(set-option :regular-output-channel "/dev/null")
(get-model)
(get-value (x (+ x 10)))
(exit)

sat
 unsupported
 (model
   (define-fun x () Real (/ 0 1))
 )
 error
