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.

I was able to reproduce this with d16-4 after creating a new Android 9.0 x86 emulator:

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

Another snippet of information.

I have two apps trying to use SpeechConfig.FromSubscription() - one is a Xamarin Forms app and another one is a Xamarin Android app.

The Xamarin Android one crashes on an x86 Oreo 8.1 emulator

@jhakulin This issue is caused by stack misalignment, caused most likely by incorrect code generated by the mono runtime. Haven't been able to find the root source of the misalignment today, but I'll figure it out next week.

BrzVlad commented Jan 28, 2020

This does not look like mono issue. All pinvokes in the Microsoft.CognitiveServices.Speech.csharp.dll are marked as stdcall while the native code from libMicrosoft.CognitiveServices.Speech.core.so appears to be cdecl. This incosistency in the call convention causes the stack misalignment. The first call that misalignes the stack is speech_config_get_property_bag
