Blender Crashes in Sculpt Mode with dyntopo while pressing `esc` key

Short description of error
Blender Crashes when I am sculpting in Dyntopo and I am in the middle of a Grab or Snake Hook drag and I hit the escape key, Blender will close out.

Exact steps for others to reproduce the error

  • Go into Sculpt mode
  • Select "Snake Hook" or "Grab" brush
  • Turn on dynamic topology
  • start pulling mesh out
    • While LMB is still pressed (or Wacom Stylus is still in contact with screen), press ESC and the application will crash

This does not occur when dyntopo is disabled. The easy solution is for me to not press ESC while doing my sculpting. Unfortunately, once in a while I will get stuck in some action regardless of where my stylus is and I hit esc in hopes of cancelling whatever action is going on. It makes me sad even though I save often.

Thank you!
