Short description of error
Some more tests done.
If there is a newly created attribute with type «Face corner + Byte color»,
pressing S in sculpt mode crashes Blender

So i suppose, the issue is initial data in this type of attribute.
Because if I paint a little, bug will not appear.

upd: the same with color. So, perhaps the issue with Face corner fresh attribute.

Bug:
