Allocatable components are not being finalized when their parent object is deallocated?

In the above the parent object is finalizable, but I think even if it wasn't (no final:: parent_Final statement) the finalizer for a%a_thing should still be called. Mentioned previously in http://software.intel.com/en-us/forums/topic/278463 and http://software.intel.com/en-us/forums/topic/284434 and possibly in other threads, so perhaps this is all well known, but I couldn't find a definitive issue id.
