Crash Reporting API and how to force a crash?

I want to see how the Crash Reporting API works and have been trying to force a crash from my app. I was under the impression that if I'm using 'Fast but no exceptions' then an exception would cause the app to crash and be terminated. This is not the case. I did manage to force a crash by calling a recursive method but the API still reports 0 crash reports.

I have enabled the API in the settings, and I'm using Unity 5.3.6.

Can anyone help?
