Multiple-thread ROS node crashes on exit when using visualization libraries

edit

Hi, I was trying to integrate a visualization library into a multiple-thread ROS node. The visualization window is created in the main thread to avoid potential issues. However, on my Macbook Pro the node still crashes when given a Ctrl-C exit. The problem happens with both OpenSceneGraph and OpenCV viz module.

Below is a minimal sample:

void loop()
{
    while (true) {}
}

int main(int argc, char** argv)
{
    ros::init(argc, argv, "some_node");
    ros::NodeHandle pnh("~"), nh;

    // osg::ref_ptr<osgViewer::Viewer> viewer = new osgViewer::Viewer;
    // viewer->setUpViewInWindow(0, 0, 640, 480);
    // viewer->frame();

    cv::viz::Viz3d window("win");
    window.spinOnce();
    std::thread thread(loop);

    ros::spin();
}

The first several lines of the crash report:
