Strange crash within [AGSLocalTiledLayer batchTilesRequestOperationSucceeded:]

Question

We're occasionally seeing crashes within our app using the latest ArcGIS SDK.
It's a EXC_CRASH (SIGSEGV) on thread 0, but no code is running on thread 0 at the time (at least in the crash report).
The common theme with all of the crash reports we're getting is a call to [AGSLocalTiledLayer batchTilesRequestOperationSucceeded:]

I've attached the full crash report. Does anyone have any ideas?

The TPK is 13GB, so can't really attach sorry.
I'm not sure what causes the crash, it's only ever our client seeing the problem.
I suspect it's when they zoom to a certain level.
What sort of issues in a Tile package might cause a crash like this?

1. If possible, can you please attach your tpk file which is being used to create the AGSLocalTiledLayer along with sample code?
2. Any idea what scenario causes the crash? Map interaction? Zoom/Pan?
