System Information
Operating system: Linux-5.15.0-48-generic-x86_64-with-glibc2.35 64 Bits
Graphics card: Quadro GP100/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 510.85.02

Blender Version
Broken: version: 3.4.0 Alpha, branch: master, commit date: 2022-09-29 09:16, hash: f1990bd900

Short description of error
This is related to the newly added auto-masking features for sculpt mode.
When using the newly added "View Normal" or "Area Normal" auto-masking features together with the Color or Cloth Filter in sculpt mode, it will immediately crash Blender.

Exact steps for others to reproduce the error

Enter sculpt mode
Use Alt A to enable "View Normal" or "Area Normal" auto-masking
Make the Color or Cloth FIlter Tool active in the toolbar
Click & drag in the viewport

Bumped priority because it's a crash introduced by a new feature.
