i couldn't get exact dates of when the bug was introduced. But it's older than the daily alpha build from the 8th of August.
**Short description of error**
When using the expand operator in sculpt mode via the shortcuts `Shift A` or `Shift W` on an open boundary, it will expand a mask or face set along the edge loop of that boundary.
In recent alpha versions of Blender this will cause a crash.
**Exact steps for others to reproduce the error**
- Delete one side of the default cube in edit mode
- Enter sculpt mode
- Use the face set expand operator with `Shift W` while pointing at the open boundary
