The second testcase is a different issue which can be reduced to:

class block {
        auto f() const -> decltype(i);
        int i;
};

name lookup in the member function's  trailing-return-type does not find
members of the enclosing class which have not been declared yet
(additionally, the diagnostic is given twice)

I think that's wrong because the trailing-return-type follows the function's
declarator-id, so [basic.lookup.unqual]p8 applies, but I'll leave Jason to
clarify that
