Uncaught exception in repeat

[minghuaw]

While working on the macro version of the ops, the following test case was found to yield an exception that was not caught before crossing the ffi boundary

    #[test]
    fn test_repeat() {
        let stream = StreamOrDevice::default();

        // We are just testing that the macros compile
        let a = Array::from_int(5);
        let _a = repeat!(a, 3, 0);

        let a = Array::from_int(5);
        let _a = repeat!(a, 3, 0, stream = &stream);

        let a = Array::from_int(5);
        let _a = repeat!(a, 3, 0, dtype = f32);

        let a = Array::from_int(5);
        let _a = repeat!(a, 3, 0, dtype = f32, stream = &stream);
    }

Since we are moving to the new error handling approach. This should not be a problem anymore, but we should add a unit test for this just to be sure before closing this issue
