Steps to reproduce:
1. Download 1115145_repro.zip
2. Build project for a standalone platform with IL2CPP backend

Expected results: Project is successfully build
Actual results: IL2CPP build fails due to "((int[])null)[0] = 1;" expression

Reproduced with: 2019.1.0a13, 2018.3.2f1, 2017.4.18f1

stdout:
IL2CPP error for method 'System.Void test::Start()' in assembly 'C:\Users\sarunas\Downloads\New Unity Project\Temp\StagingArea\Data\Managed\Assembly-CSharp.dll'
