[Android] Crash on builds with .NET 4.6 scripting runtime selected when null reference exception appears



To reproduce:

1. Download and open attached "" project.
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

Devices under test:

Reproduced with:
Lge LG H815 (G4)*, OS:6.0, CPU:arm64-v8a, GPU:Adreno (TM) 418,

Samsung SM G800F (Galaxy S5 Mini)*, OS:6.0.1, CPU:armeabi-v7a, GPU:Mali-400 MP, Build:samsung/kminiltexx/kminilte:6.0.1/MMB29K/G800FXXU1CQA1:user/release-keys

Google Pixel*, OS:8.0.0, CPU:arm64-v8a, GPU:Adreno (TM) 530,

Not reproduced with:
HUAWEI EVA L19*, OS:7.0, CPU:arm64-v8a, GPU:Mali-T880,

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.
