2. Build and run for android device.

Expected result: Application loads up correctly, without crashing.
Actual result: Application crashes instantly after it's loaded.

Reproduced with: 2017.3.0b2, 2017.2.0f2, 2017.1.1p3, 2017.1.0a6
Not reproduced on: 2017.1.0a5 - new .NET4.6 not present

iPad Mini 3 (iOS 10.3.2)

Notes: Calling "throw new NullReferenceException()" does not trigger the crash. If Scripting runtime version is set to Stable( .Net 3.5 Equivalent), everything works as expected. Does not happen when Scripting backend is set to IL2CPP.

    This bug can be reproduce in some env, like if you are using universalmediaplayer plugin(which has a native library. if you are using this, null ref will make app crash with no hint in android.

    I have tried 2017.2.2p1, 2017.4.3f1,alll crashed, but all ok on il2cpp backend which is strange. And IL2CPP have lot's of other problems.
    Plz Fix it.

    We are experiencing this or a similar issue: some exceptions crash the app on Android when using .NET 4.6. Enabling the "Script Debugging" build option prevents the crashes (but is obviously not a reasonable option to use for production builds).

    Can reproduce on Unity 2017.1.1f1 and 2017.1.2p1 on Google Pixel (Android 8.0.0).

    On the company I work at I've noticed a pattern: On android phones with OS 7, Nougat (and/or higher), the crash doesn't happen, on the lower ones it always does.
    Also, surrouding erratic code with try catch does not help.

    Please.
    Fix.
    This.
