cv::viz::viz3d Crashes soon after Mouse Interaction OS X

edit

I'm am trying to run a cv::viz thread outside of my main thread to visualize a stream of 3D points.

Notice that missing are the typical 3 buttons for close, minimize, and expand. The main loop looks as follows:

  cv::viz::Viz3d vizWindow( "Coordinate Frame" );

  while( isActive() && !vizWindow.wasStopped() )
  {
    points3dFrame = m_points3dBuffer.waitNewFrame( lastTimepoint );
    lastTimepoint = points3dFrame->timepoint;

    std::vector<cv::Vec4f> cloud = filterCloudByDepth( points3dFrame );

    if( cloud.empty() ) { continue; }

    auto cloudWidget = cv::viz::WCloud( cloud, cv::viz::Color::green() );
    cloudWidget.setRenderingProperty( cv::viz::POINT_SIZE, 2 );

    vizWindow.showWidget( "Depth", cloudWidget );

    vizWindow.spinOnce( 30, true );
  }

This runs as desired when built with VS2012 and run on windows. However, when I try to run this built with Xcode 7.2 tool on OS X 10.11.4 it will crash soon after I try to interact with the window using my mouse, with warning logged to the console before crashing.

Any idea why this fails? Do I really need to put this in my main thread? Why is it ok not to do so on Windows?

Errors to console:
