That's illegal, because Some_Array'Length denotes a value,
not an object, so you can't use it like that in an
object_renaming_declaration.  GNAT correctly detects
this error.  I don't see any mishandling here.
Am I missing something?

I would prefer to allow the above, but that's a language issue,
not a compiler issue.  And it's certainly not an issue specific
to the back end.

Not sure what you mean by that.
