Description Adam Hartley [MSFT] 2016-07-12 10:32:59 UTC
## Steps to reproduce

Build and run app on a device - during my testing it appeared to be crashing on 32-bit devices only (see XTC link in next comment)

## Expected result

App should not crash

## Actual result

App crashes on 32-bit devices

## Notes

Customer is building with Mono 4.2 and appears to have the app crash on iPhone 4s (9.1) and iPhone 6s (9.0.2). During my own testing, I built the app with Mono 4.4.2 and the app ran fine on iPhone 6s devices (and all other 64-bit devices)
