Shader Compiler crashes when using Interlocked* methods in pixel shader
Reproduction steps:
1. Open the attached "case_1310201.zip" project
2. In the Project window, select Test.shader and compile it
3. Observe the Console window
Expected result: There are no errors
Actual result: Shader compiler errors appear
Reproducible with: 2018.4.32f1, 2019.4.20f1, 2020.2.4f1, 2021.1.0b6, 2021.2.0a4
Note:
1. Tested and reproduced the issue with InterlockedMin(), InterlockedMax(), InterlockedAdd(), InterlockedAnd() methods
2. Reproducible with Direct3D11, Direct3D12, Vulkan, OpenGLCore, OpenGLES2, OpenGLES3 Graphics API's
3. Errors:
"Shader Compiler IPC Exception: Terminating shader compiler process"
"Shader error in 'Hidden/Test': Internal error communicating with the shader compiler process"
"[Worker0] Shader compiler: Compile Hidden/Test - <Unnamed Pass>, Fragment Program: Internal error communicating with the shader compiler process. Please report a bug including this shader and the editor log."

Resolution Note (2021.2.X):
This is a crash in the 3rd party compiler we use. We cannot really do anything about it, unfortunately. As a workaround I would suggest doing the same in compute instead of a fragment shader.
