This means that by following a chain of one or more pointers from a finalizable object f, you can get back to f. It means that f''s finalizer would unavoidably see a partially finalized object if it were run, and thus isn't.
You may be calling GC_register_finalizer where you meant GC_register_finalizer_ignore_self, and thus getting caught by pointers from the object to itself, e.g. to implement C++ multiple inheritance.

Subject: [Gc] What does "Finalization cycle" mean?
I'm getting this message in my otherwise working C++ program: GC Warning: Finalization cycle involving 2ab1a897bbd0
Does anyone recall what this means? I don't currently believe that my data structures have any cycles in them.
