Need help to understand following crash log - ios

Question

I am experiencing a strange app crash. I narrowed down the problem to one particular visual component. The app crashes when i navigate back and forth to the screen with this component several time. The strange thing is that same component does not cause crashes on another screen. The problem is that the app does not throw any error when running in debug more. The only thing I see is the crash report in device's log.
I am not sure what code from this component should I provide here. Thus, I will describe what it does in general words. Majority of the layout is coded in xib file which I am loading at runtime. This xib file has number of controls, and UIScrollView is one of the main container. At runtime, I am adding few more UIViews to this scroll view. I am also performing some custom drawing on main CALayer of these added UIViews.
It would be create if somebody can help me narrow down the problem. Also, how can I get more precise report if the issue does not throw any exceptions during debugging?
UPDATE1:
I did further investigations and I think the problem can be narrowed to possibly incorrect disposing. Very similar case is described here (the first comment under the answer). https://stackoverflow.com/a/5359686/3507404
UPDATE2:
It happened that the crash is related to CALayerDelegate. I narrowed down the issue to simple example here. CALayerDelegate disposing issue
