App crashes with debugger attached

[Cheesebaron]

Steps to Reproduce

1. Debug app
2. App crashes randomly

Expected Behavior

App runs without random crashes

Actual Behavior

When the App crashes it outputs a crash report, without having any useful stack trace to the App being at fault.

=================================================================
	Native Crash Reporting
=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

I got some help from @grendello to debug the issue and tried the following:

1. Adding an environment.txt file to the App to increase what is being logged. That yielded the following log:

2. @grendello then asked me to try run the App with lldb. However, I didn't get that to work, it just made my App hang on splash screen and left some props on the device that made the subsequent launches of the app fail. I followed the instructions here: https://github.com/mono/lldb-binaries had to mess with the xa-lldb script to make it pick up the correct Main Activity and make it use msbuild because xabuild is not present on my machine.

3. After the failed lldb attempt, @grendello asked me to run msbuild /bl /t:_Gdb on the App project, which didn't seem to crash the App. Which lead @grendello to the conclusion: "that means it might be a problem with sdb or triggered by it". And here we are.

I cannot attach a repro sample, because I don't know which part of it actually triggers the App to blow up, since there is no stack trace to go from.

This issue seems to mainly happen on arm64 devices. My Nexus 5, doesn't have any issues with debugging.

Other people on Gitter.im had a similar issue.

Please let me know if I can provide further details to assist with the debugging.

@lambdageek here is how I was able to reproduce (hit me up on Slack if you need more info):

1. Clone this repo and open XamarinFormsControls.sln: https://github.com/dotMorten/XamarinFormsControls
2. Debug SampleApp.Android.csproj
3. Click the first button, Simple Auto-Completion
4. Type a few characters in Enter a country, hit back arrow
5. Repeat on step 3

You might have to do the cycle one time or more.

Once the app crashes, you can just launch the app by tapping the app icon. The crash seems to go away when no debugger is attached at all--no changes in app settings required.
