System Information
Operating system: Linux-5.8.0-25-generic-x86_64-with-debian-bullseye-sid 64 Bits
Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 455.32.00

Blender Version
Broken: version: 2.92.0 Alpha, branch: master, commit date: 2020-11-05 07:27, hash: 7bc7b7da2d
Worked: blender-2.92.0-564f3be20a6f-linux64 from Buildbot

Short description of error
Cycles rendering of a Volume Object instantly crashes Blender.
I reported a crash with volumes while preview rendering and changing the current frame a few weeks ago which was fixed. Now the crash seems to be back with a vengeance because it even crashes without the need to change the frame or scrub the timeline.
The 564f3be20a build from yesterday works flawlessly. Today's build fails as do my own builds of master.
Quick side note that might help:
Yesterday night when the crash occurred the first time with the latest builds I tried to narrow down the guilty commit. I did a git checkout 564f3be20a to compile the same build as the last working Buildbot build but still my build crashed. I noticed I had NanoVDB enabled. So I unchecked that option and rebuilt and voila it worked.
So it might be related to NanoVDB somehow? But did something change between yesterday's build and today's?

Exact steps for others to reproduce the error

Download the blend file
Volume_Object_Crash_v01.blend
Open and set the viewport to preview render
Rendering tries to start but stalls during the "Updating Mesh" phase for 1-2 seconds
Crash

I built this scene as simple as possible and used the Mesh to Volume modifier. But it also successfully crashes with VDBs.

This is a different crash which was introduced by my refactor.
