Sorry to be replying to my own e-mail, but I figured it out...
GSEQ_STRCOMP() calls -rangeOfComposedCharactersAtIndex: and CFString was
just returning {0, 0} for that call. I still can't really follow what this
function does, but that seems like a weird method to call since NSString
just return {0, 0}, as well, and it would break any NSString subclass that
doesn't specifically override this method.
After fixing this function in CFString the tests are now all passing.
