6.7.3.2p12 [133:20-21] says that implicit synchronization occurs when a
coarray subcomponent is automatically deallocated as a consequence of
execution of a RETURN or END statement or a statement that causes
termination of a BLOCK construct. Is this true? And what does "coarray
subcomponent" mean here anyway? Is it "subcomponent that is a coarray"
or "subcomponent of a coarray, which cannot be a coarray"? Why doesn't
"deallocation of a coarray" just cover this?
Is a subcomponent of an object ever implicitly deallocated without the
object itself being deallocated (6.7.3.2p2-3 don't say so)?
Does deallocating a subcomponent of a coarray by a DEALLOCATE statement
cause synchronization (6.7.3.2p11 doesn't say so)?
Does allocating a subcomponent of a coarray by an ALLOCATE statement
cause synchronization (6.7.1.2p4 doesn't say so)?
