Weird behavior in Rust with OpenCV

I am trying Rust (ver 1.4.0) these days, and coding with opencv-rust library.

I wrote some code like this.

extern crate opencv;

use self::opencv::highgui;
use self::opencv::core::Mat;

fn main() {
    load("image/test4.jpg");
}

fn load(path: &str) {
    let src: Mat = highgui::imread(path, 1).unwrap();

    if src.empty().unwrap() {
        println!("Img load error");
    }
    else {
        println!("Img load success");
    }
}

When I run cargo run it shows Img load error.

However, when I added a println! at first line in load function like

fn load(path: &str) {
    println!("whatever");
    let src: Mat = highgui::imread(path, 1).unwrap();

    if src.empty().unwrap() {
        println!("Img load error");
    }
    else {
        println!("Img load success");
    }
}

It shows Img load success.

But when I change it to other code like let a: i32 = 1;, it shows Img load error again.

I have no idea what's going on.
