Short description of error
Crashes Expand Active Face Set operator with Multires subdiv. It must have at least one multires subdivision active, otherwise it's fine.

Exact steps for others to reproduce the error

Factory Startup
Select cube
Add multires modifier
Go into sculpt mode
Subdivide with multires
Expand Active Face Set in Face Sets dropdown menu
Click Subdivided cube.

Notes:
Oddly enough it doesn't crash all the time? blender_sculpt_expand-works.blend
I've tried adding facesets before and after subdiving with Multires.. Seems to crash less if facesets were added before subdividing, but it's still a 50/50 when using 'Expand Active Face Set'. Sometimes its a certain faceset instead of all facesets that will make it crash when using the operator.
