Short description of error
Hard crash, after Particle Edit

Exact steps for others to reproduce the error
Hair editing, completed, Disconnect Hair (or Discount All) F12 to Render, full crash.
I have not been able to find out how to "Commit" the Edits to the Particle Hair edits, so I can go back and increase the Number.
Did a Google search on variations of this topic. Tried the Disconnect Hair as a last choice, Render, Crash.

I have uploaded the file, which now crashes immediately. Open the file, press F12, watch Blender disappear.
I did not even try the Disconnect Hair or the Disconnect All, just Open, F12, Crash.
Hope this helps.
I appreciate the development, congratulations on the RC release.

Successfully opened the file, and chose Object Mode, instead of Particle Edit mode, was able to F12 Render. Apparently the crash is only in Particle Edit Mode. Still haven't figured out how to "Commit the Edits" of the Particle Edit, so I can go back and increase the number of Hair Particles??
