System Information
Windows 10, GTX 1070

Blender Version
Broken: Blender 2.8 Alpha 2, 74737091c0

Short description of error

Blender crashes either the first time baking, or after a few bake, clear and re-bakes.

Exact steps for others to reproduce the error

Start a new Scene
Select the default cube ( probably already selected )
Open the Physics Tab
Select "Smoke" and Type "Domain"
Shift A and add a UV Sphere
In the Physics Tab, select "Smoke" and "Flow"
Reselect the Cube, and go to the Cache tab in the Physics section

Note that the buttons for caching can't be selected until you save.

Save the scene
Select "Bake"

If Blender doesn't crash...

Select "Free All Bakes"
GOTO 9 :)

I've attached the simple .blend file, start at 9) if you're using it.Smoke_Baking_Crash.blend

Also happens when baking hair dynamics or soft body physics. I get an immediate crash when pressing the "bake" button.

Tested on Blender 2.8 c4c62e6df5, Windows 10, GTX Titan X

Confirmed.
Not sure this is a leftover from #56352, needs further investigation...

Hi Brecht,

It would be great if the results of the last baked frame could be seen as the timeline is updating ( so that the artist could proof the results as baking is taking place, so that they can cancel and re-do ).

Currently they would have to wait until the end of the bake, and then play, to see the results.

@MalDuffin, agreed, but at the moment we are focusing on getting physics functional to 2.79 level. Seeing the baked results update requires deeper changes.
