ofVideoPlayer makes the app not responding after a while if (especially large) video file are reloaded.

app stalls/blocks and osx multicolor wheel starts rotating after a while if movie files are (re)loaded.
The problem happens with frequent reloading (every 2 or 3 update calls or after played 2 or 3 frames checking getCurrentFrame) and sooner with large video file (2 GB). This happens to me after few seconds or several minutes depending on video size and reloading frequency. Note that this makes the app blocking faster, but i experienced this problem even with loading a clip on a movie loop video with a sensor input (i.e. randomly).
A small video file (50 MB) blocks the app if loaded after few update (reloadUpdate=2 in the example below), just after the previous one ( if myMovie.isLoaded(){load another one} ) or after the movie is loaded and played a bit (a couple of frames, reloadAfterFrame=2)
A big video file loading blocks the app sooner even with not so fast reloading frequency (i.e. reloadUpdate=20 or reloadAfterFrame=20).
Also when the app freezes the memory allocated (in the activity monitor report) doubles (it's not releasing the previous movie? anyway even if i close the movie before loading a new one things don't change).
I start experiencing this problem with version 0072, now i'm using v008, v0071 works fine to me.

void testApp::setup(){
    ofSetVerticalSync(true);
    currMovie=0;
    myMovie.loadMovie(ofToString(currMovie)+".mov");
    myMovie.play();
    changeMovie=0;

    reloadUpdate=20;// =2 this blocks sooner the app
    reloadAfterFrame=20;// =2 this blocks sooner the app
}

//--------------------------------------------------------------
void testApp::update(){
    changeMovie++;
    if (changeMovie>reloadUpdate)
   // if (myMovie.isLoaded() && myMovie.getCurrentFrame()> reloadAfterFrame) 
    // checked also if movie was loaded and played some frames, same result
    {
        cout <<"reload "<<ofToString(currMovie)<<".mov"<<endl;
        changeMovie=0;
        currMovie++;
        currMovie=currMovie%3;
        myMovie.loadMovie(ofToString(currMovie)+".mov");
        myMovie.play();
    }
    myMovie.update();

}

Start at the ofVideoPlayer loadMovie/update entry points and reproduce the issue using the setup() and update() example with repeated reloads of the three movie files. Compare behavior across the reported openFrameworks versions on macOS. Done means repeated reloading no longer stalls the app or causes the reported memory growth.
