Christoph,

Your article is about the fact that primitive operations can only
override visible operations of a parent type.

Although I take your point, in my case the operations were in a child
package -- exactly like yours! -- so the inheritance from
Ada.Finalization.Controlled should have been visible.

Interestingly, when I made the inheritance public, Apex crashed in the
"middle pass" (AFAICR).
