1) add a polygon layer
2) a column proper to receive values for the polygons areas, use the field calculator to compute them
3) to this column set a default to "$area" and check the "apply default value on update" option
4) split a polygon >
the area for one of the newly created polygon is correctly computed and added to the table > ok
the area for the other polygon is not updated/recomputed.
Technically is not data corruption nor a crash, but this leads to wrong results... so this should really be a high priority ticket, I think.
