AIR app crashes on iOS after returning from CameraUI photo capture

Question

So, I've been running into this problem in one way or another for as long as we've had CameraUI access. It seems that each time another version of AIR comes out Adobe claims the problem has been fixed, and each time I find that the problem hasn't. So, here we go:
I'm running an AIR 3.4 application on a range of devices: iPod Touch (previous generation), iPhone 5, iPhone 4S, iPhone 4, and iPad 2. All the test devices are loaded with the latest version of iOS. On every one of them, if the user takes a few photos in a row the application crashes by quietly returning to the desktop. On Android devices, the same happens when I take even a single photo. In fact, when running the application in the debugger I can see that the process terminates not when the app returns from CameraUI, but as soon as the native Camera is invoked.
This problem has been going on forever. What is the fix?

Answer 1

Just going on your original post about Android quitting as soon as the camera is invoked I did a quick test.
FB Test code:
package
    import flash.display.Bitmap;
    import flash.display.Loader;
    import flash.display.Sprite;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.events.Event;
    import flash.events.IOErrorEvent;
    import flash.events.MediaEvent;
    import flash.media.CameraUI;
    import flash.media.MediaPromise;
    import flash.media.MediaType;
    public class TestingCameraRoll extends Sprite
        private var cam:CameraUI;
        private var _imgNum:int = 1;
        public function TestingCameraRoll()
            super();
            stage.scaleMode = StageScaleMode.NO_SCALE;
            stage.align = StageAlign.TOP_LEFT;
            addEventListener(Event.ACTIVATE, _onActivated);
        protected function _onActivated(event:Event):void
            removeEventListener(Event.ACTIVATE, _onActivated);
            trace("App activated, starting camera.");
            cam = new CameraUI();
            cam.addEventListener(Event.CANCEL, _captureMobileCancel, false, 0, true);
            cam.addEventListener(MediaEvent.COMPLETE, _captureMobileComplete, false, 0, true);
            cam.launch(MediaType.IMAGE);
        protected function _captureMobileComplete(event:MediaEvent):void
            trace("_captureMobileComplete: " + event.type);
            var mp:MediaPromise = MediaPromise(event.data);
            var imgLoader:Loader = new Loader();
            imgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, _imgLoadHandler);
            imgLoader.addEventListener(IOErrorEvent.IO_ERROR, _errHandler);
            imgLoader.loadFilePromise(mp);
        protected function _imgLoadHandler(event:Event):void
            trace("imgLoadHandler - width:" + event.target.width + " height:" + event.target.height);
            var bm:Bitmap = new Bitmap(Bitmap(event.target.content).bitmapData);
            bm.width = stage.fullScreenWidth;
            bm.height = stage.fullScreenHeight;
            bm.name = "img_" + _imgNum++;
            addChild(bm);
            trace("Added image: " + bm.name);
            cam.launch(MediaType.IMAGE);
        protected function _captureMobileCancel(event:Event):void
            trace("Capture cancelled")
        protected function _errHandler(event:Event):void
            trace("Error: " + event);
All that does is continuously request to take a picture and then dump it on the display list at full size. I didn't do proper size/orientation compensation, I just sized down so I could verify it took the photo. The goal was to #1 successfully load the camera, #2 take a picture, #3 receive the data, #4 pile them up in full resolution (albeit scaled) on the display list without crashing.
My SGS3 started to get slow after 15 pictures but here's the trace:
App activated, starting camera.

App never crashed, and this is running in debug mode. That's 15 8MP full size images stacked on the display list.
I use AIR 3.5 release on this (3.5.0.600, not even the latest 3.5.0.880).
