Compute shaders using glsl reserved words fail to compile when using Vulkan Graphics API

--

-

Reproduction steps:
1. Open the attached “repro-project“
2. Open the Assets/Test.unity scene
3. Observe the errors in the Console

Reproducible with: 2023.1.2f1, 2023.2.0a21
Could not test with: 2021.3.28f1, 2022.3.4f1 (could not downgrade the project)

Reproduced on: Windows 10 Pro

Notes:
1. Not reproducible on DirectX12 Graphics API
2. The following errors are displayed in the Console:

”Shader error in 'Test': glslang: '' : compilation terminated at kernel ToTex at line 26 (on vulkan)”

”Shader error in 'Test': glslang: 'input' : Reserved word. at kernel ToTex at line 26 (on vulkan)”

”Test.compute: Kernel at index (0) is invalid
UnityEngine.ComputeShader:Dispatch (int,int,int,int)
Test:Start () (at Assets/Test.cs:24)”

  1. Resolution Note (2021.3.X):

    Backporting this fix would require more time than usual, since some foundational code doesn't exist on this version. Users can work around the bug by not using words reserved in GLSL in their shaders.
