So the base addresses are in the skeleton and the actual section
can go with Split Full (i.e, in a .dwo) if it has no addresses but must
go with the skeleton if has addresses.
This way the standard is not in error as written.? This understanding
restricts what information can be derived from
the Split Full CU by itself (ie, without the skeleton) a bit since the
base addresses are not in the Split Full CU DIE.
Mike Eager: please delete the new issue 200831.1 as it is simply wrong.
