~~This 4f9e21bdc9 might be the bad boy.~~
EDIT: No, can't be. The time doesn't match, no?

Fixed by c4f8aed, same underlying cause.

@brecht I think this was incorrectly closed, it still crashes when rendering on the CPU with OptiX denoiser enabled.

I am able to reproduce with nightly build Blender 2.92.0 Alpha January 01, 00:24:12- 0da1fc2fc4 Windows 64 bit
blender_debug_output.txt
2020-12-18_optix_denoise.crash.txt
blender_system_info.txt

But Curiously it does not reproduce with my local "Release" build sync'd to the same commit as the nightly build.
