Short description of error
Adding hair in Particle Edit causes crashes randomly

Exact steps for others to reproduce the error

Open this .blend: manII_5_export.blend
In Particle Edit mode, try adding some hairs. You may need to change a few settings (count, brush size etc.). Eventually it will crash for seemingly no reason.

This one seems to be a long-standing issue with the Add brush (is in 2.79 even).
Using the particle Add brush with a radius > 181px will result in a freeze (hangs in brush_add_count_iter due to short overflow.)

Fix incoming...

Whoa that was fast! Thanks so much Philipp.

I tested it in 2.83.1 (didn't realize there was an update) and it hasn't hanged yet. But glad you've committed a fix. Hopefully it's gone for good :)
