Yes it happens not very frequently. A far more probable issue when the
count has to be checked against 0 is in the Finalize of counted objects. If
you discover that the count is not zero, that is a serious problem. This
happens very often upon exception propagation when there are still
outstanding references and the compiler calls Finalize because something
(some type for example) goes out for the scope. There is a funny rule that
the compiler has to maintain a list of controlled objects and call Finalize
on its own when you least expect it...
