System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.38

Blender Version
Broken: version: 2.92.0 Alpha, branch: master, commit date: 2021-01-12 20:03, hash: 719bea0d6d
Worked: (newest version of Blender that worked as expected)

Short description of error
NLM denoiser with large tiles causes instant crash and exit.

Exact steps for others to reproduce the error

Start Blender.
Change render engine to Cycles.
Device to GPU.
Enable Denoising pick "NLM" for Render.
In Performance->Tiles option change both for Tile X and Tiles Y to 2000.
Change scene Dimensions both for Resolution X and Resolution Y to 2000.
Click "F12" for rendering.

I am working with large tiles for performance reasons my GPU 3090x and CPU with 64gb has plenty of memory. This tile size work fine with the denoiser for "Optix" and "OpenImageDenoise" and have no problem.

I can confirm this crash in current master. I don't have time to investigate this further today, but I will take another look tomorrow.
