Crash with Android x86 emulator and Microsoft CognitiveServices Speech Xamarin quickstart

[jhakulin]

Steps to Reproduce

1. Download Microsoft.CognitiveServices.Speech SDK helloworld Xamarin quickstart from https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/quickstart/csharp/xamarin
2. Build the solution and start debugging it on Android x86 emulator
3. After app is launched, press "Enable Microphone" button and agree with consent and then press "Start Speech Recognition" button

Expected Behavior

App would start speech recognition and would not crash

Actual Behavior

App crashes based on my analysis in mono runtime, root cause is not known.

The crash in OP suggests it's an issue with the Mono JIT.
