How to reproduce:
1. Create a new project with URP or HDRP template
2. Import the Unity Recorder package from the Package Manager
3. Make sure to close the Profiler window if it was already opened and reopen it again (Window -> Analysis -> Profiler)
4. Enter Play Mode
5. Select any frame recorded in the Profiler window

Expected result: GC.Alloc in PlayerLoop -> RenderPipelineManager.DoRenderLoop_Internal() is equal to 0 bytes
Actual result: GC.Alloc is equal to 40 bytes in every single frame (even when not using Unity Recorder in any way)

Reproducible with: 2.0.0-preview.6 (2019.4.4f1), 2.1.0-preview.1 (2020.1.0b16), 2.2.0-preview.4 (2020.2.0a18)
Could not test with: 2018.4.25f1 (GC.Alloc is already equal to 2.4 kilobytes without the Recorder package and it's unclear whether the 40 bytes are added to it when it's installed)

Notes:
The issue doesn't occur when creating a project without URP/ HDRP template and importing the package through the Package Manager
