Worked: Not sure
When creating a particle simulation that runs for some time a large point cache can be created. This can be read from and written to fine during the session in which it is created. If you save the scene to a .blend file and try to open it Blender crashes with an exception violation. --factory-startup makes no difference. Appending to a new scene also fails in the same manner. This renders the file inaccessible and any work in it is lost.
On my system if I:
- Launch Blender with the default scene
- Add an Emitter particle system to the cube
- Set the Emission Number to 100,000
- Set the animation timeline end to 1440
- Bake the cache
- Save the .blend file
- Try opening the same file
Running with --debug-all from the command line I see this at the end of the transcript:
