Could you expand the test with all the different permutations ? Specifically
test:
(NSAttributedString *) CFAttributedStringRef
(NSAttributedString *) CFMutableAttributedStringRef
(NSMutableAttributedString *) CFAttributedStringRef
(NSMutableAttributedString *) CFMutableAttributedStringRef
(CFAttributedStringRef) NSAttributedString *
(CFAttributedStringRef) NSMutableAttributedString *
(CFMutableAttributedStringRef) NSAttributedString *
(CFMutableAttributedStringRef) NSMutableAttributedString *
then also repeat the above with another set of types _without_ the presence of
the internal struct definition (without the equivalent "struct
__CFAttributedString {};”)_______________________________________________
