unity3d - Build crash with custom shader, Unity.exe access violation

Question

Trying to compile my project with custom shaders results in the Unity IDE crashing during build process.

I've got two custom shaders for terrain that seems to be the root of the problem.

What I've done:

• Checked error logs, reports access violation in Unity.exe, with stacktrace pointing to BuildPlayerRenderPipeline
• Changed shader of terrains to Nature->Terrain->Diffuse. This works fine.
• Run Unity Editor as admin, no change.
• No error codes on Shader code in Editor

See the attached (most critical) shader below. The second one is very similar.

Shader "Custom/HueTerrainShader"
{
    Properties
    {
        _MainTex("Base (RGB)", 2D) = "white" {}
        _Color("Alpha Color Key", Color) = (0,0,0,1)
        _HeightMin("Height Min", Float) = -1
        _HeightMax("Height Max", Float) = 100
        _HSVRangeMin("HSV Affect Range Min", Range(0, 1)) = 0
        _HSVRangeMax("HSV Affect Range Max", Range(0, 1)) = 1
        _HSVAAdjust("HSVA Adjust", Vector) = (0, 0, 0, 0)
        _Opacity("Opacity", Float) = 1
    }
