I started seeing these crashes very recently and I also updated my mono very recently. I'm using Mono JIT compiler version 4.6.0 (mono-4.6.0-branch/7c372ff Thu Jul 14 02:56:23 EDT 2016) at the moment. This could be a regression in C8 mono.

***************** Reproduce Status ***************** I have tried to reproduce this issue with larger solution with Mono 4.6.0. I have typed multiple times to search box for searching text and used keyboard arrow keys. After using arrow keys, XS get crashed. I am able to reproduce the XS crash behaviour around 3 times but I am getting different exceptions "ObjCRuntime.RuntimeException: Cannot register two managed types " IDE Log: https://gist.github.com/shrutis360/fa88a07a785809e044bf104413c48b20 XS Crash report: https://gist.github.com/shrutis360/58f9a81bfb0cdc1dae7c2f1042ebc35a Environment Info: https://gist.github.com/shrutis360/ee87aa52f0f4db66265318690c1998d7 Screencast: http://www.screencast.com/t/W1tPISiVD1S **************** Verify Status: ***************** I have checked this issue with patch Mono 22.214.171.124 with multiple behaviour of typo text in search box and used keyboard arrow keys. And XS did not get crashed. Environment Info:https://gist.github.com/shrutis360/2083aadfc7cb14e760b997234fbaaadc @Alan, Could you please review it. And I believe we can verify this issue as this issue is no more exist.

You triggered the issue with the old build and couldn't with the fixed build, so that looks like the patch worked as expected!

I have verified this issue with the latest Cycle 8 builds, below is the environment information for the same: https://gist.github.com/jatin360/bbda969e4628e7aa504070cbcec8e9e0 I have observed that this issue is now foxed, as the XS does not crash when type text in search box and used keyboard arrow keys. Below is the screencast for the same: http://www.screencast.com/t/FIRfp8pM Hence, we can close this issue.
