[TIMOB-3631] Crashing after continued use

After continued use of the app it will crash. All crashes result in a kill 9 with no further logs or crash statements. Tested on 1.6.3, 1.6.1, 1.7CI. The general design of the app: The app is One universal scrollableView. When a section (i.e. Entertainment, Local, World, etc.) gets loaded the views array gets flushed out (set to null) and repopulated with the new data. Reproducing the crash is as easy as refreshing a section 20 or so times or the following.... Reproducible Steps: Test Case One: Refresh the home page 20 times Test Case Two: Click the section button next to refresh -> Select a new section -> repeat selecting different sections -> refresh a section or two -> will result in crash after so many times. Test Case Three: Tap Section button next to refresh -> Select Entertainment -> Refresh 4-5 times to crash. Test Case Four: Load a section -> Tap on an article -> scroll through other articles -> Load a section -> repeat --- Also, there is an issue with scrollableViews and 1.6.3. You cannot set the views array to null or it will throw: ~~~ message = "Invalid type passed to function. expected: NSArray, was: (null) in -[TiUIScrollableViewProxy setViews:] (TiUIScrollableViewProxy.m:32)"; sourceId = 202632936; ~~~ Note that setting the views array to null in 1.6.1 doesn't resolve the kill 9 crash.
