How to reproduce:
1. Create a new project
2. Install the "High Definition RP" package from the Package Manager (Window > Package Manager)
3. In the Project window select Packages/HDRP/Runtime/Materials/Lit/Lit.shader
4. In the inspector, enable "Preprocess only" and disable "Strip #line directives"
5. Hit the small triangle next to "Compile and show code" to expand the menu and select "All platforms"
6. Click "Compile and Show Code"

Expected result: File grows as big as needed and contains all data
Actual result: On Windows code randomly stops being printed mid-line and file size is 2,097,153KB

Reproducible with: 2020.3.22f1, 2021.1.28f1, 2021.2.2f1, 2022.1.0a14
Could not test with: 2019.4.30f1 (option "Preprocess only" is missing)

Notes:
- Seems to only happen when the preprocessed file is close to or above 2GB, on Windows this files' size is capped at 2,097,153KB
