System Information
Operating system: Windows-7-6.1.7601-SP1 64 Bits
Graphics card: GeForce GTX 960/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.86

Blender Version
Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-07-18 14:52, hash: 38d4483c6a
Worked: (optional)

Short description of error
Blender crashes to desktop with no alert when switching back to Object mode from Sculpt mode. Happens most often after using the Snake Hook brush extensively while in Dynotopo at higher poly counts, although Dynotopo itself is the more likely culprit. Happens around 30% of the time for me.

Exact steps for others to reproduce the error

  1. Open any model 100k faces or more
  2. Enable Dynotopo and set detail to constant/use the eyedropper or slider to set the value to ~20+
  3. Sculpt using the Snake Hook brush
  4. With Snake Hook Brush still selected, switch the viewport mode to "Object"

Does this still happen with the latest build? https://builder.blender.org/download/

Seems to be resolved in 2.8 final. After several tests, I'm getting no more crashes
