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 461.92
CPU: Intel Core i7-8700K
Memory: 32 GB

Blender Version
Broken: version: 2.92.0, branch: master, commit date: 2021-02-24 16:25, hash: 02948a2cab
Worked: I have not tried any other version than 2.92.0 (sorry)

Short description of error
I tried to make a simple steam simulation following the steps described here: https://www.youtube.com/watch?v=_K0XsHht6pg. It crashed while baking, and tried to simplify the setup with a minimal set of objects, and it still crashes after baking about 30-50% of the 300 frames.

Exact steps for others to reproduce the error
Follow the steps as described in the video https://www.youtube.com/watch?v=_K0XsHht6pg

Attached is .blend file that I tried to make as simple as possible: steam.blend

Open the attached file
Press "Bake Data" for Physics Properties for the cube
Blender crashes after 30%-50% of baking

I have not tried a newer experimental release or an older release.

I was able to reproduce the issue with the default 32 Resolution Divisions (which is way faster to reproduce than the 160 in the included file). I then tried experimenting which exact setting caused the crash. I got it to crash with Adaptive Domain disabled, and Gas Heat 1.5 and Dissolve Time 30, but now I'm not able to reproduce anymore with any setting (at least with 32 Resolution Divisions).

After some more experimenting, it seems it randomly crashes and sometimes works. It is definitely reproducible with 32 Resolution Divisions. I kept all settings as I had before, which had worked successfully, but then changed the Time Scale to 0.8, and then it crashed again when baking. However, it had previously crashed at least once with the exact same settings with which I had also successfully baked (and the Time Scale at the default 1.0), so it is not the Time Scale that is causing the issue.
