[Critical] Comparing a value from a multi-dimensional array in a frag shader causes the shader compiler process to crash
How to reproduce:
1. import the minimal shader attached in comment to any project (NewUnlitShader.shader (889 bytes))
2. Reimport the shader file
Expected results: The shader gets successfully compiled
Actual results: The shader compiler throws a "Fragment Program: Internal error communicating with the shader compiler process." error
Reproducible with: 2018.4.10f1, 2019.2.7f2, 2019.3.0b5, 2020.1.0a7
Note: The issue is caused by line 63 in the shader:
_VoxelArray[0][0][(int)i.objVertex.z];

Resolution Note (2020.2.X):
The _Voxels array declared in the global scope takes more than 64KB of data. Please use a StructuredBuffer or a texture to access this data instead.
