Unexpected char: <

[Dejan Jovanović]

Running the solver on the problem below I get a parse error.

(set-logic QF_LIA)

(declare-fun x () Int)
(declare-fun y () Int)

(assert (and (<= 0 x) (<= x 10))
(assert (= y (# u Int (= y x)))

(check-sat)
(get-model)

The error is

dejan@pup:~/workspace/counting-smt$ ./solver.native --verbose < ./examples/test04.smt2
 -> (set-logic QF_LIA)
 -> (declare-fun x () Int)
 -> (declare-fun y () Int)
Fatal error: exception Lisp_lexer.SyntaxError("Unexpected char: <")

If possible it would be good to output some more info on the error.
