It comes about when nested modules use the same use associated symbol at 
module level and in a contained function.  The ICE came about in the 
original PR because some of the references would stick to the contained 
version.  This trick promotes those references up to share a common 
symbol in the parent namespace.

Specifically difficult are derived type specifications that are used to 
type formal arguments of a contained function; the original PR.

In short then, you are right but this particular case blurs the 
distinction a bit, from the practical point of view.
