--- Comment #2 from Paolo Carlini <paolo.carlini at oracle dot com> ---
Pretty sure it's my change because typeinfo::before and typeinfo::operator==
are special on some targets and I couldn't notice on x86-linux:

#if !__GXX_TYPEINFO_EQUALITY_INLINE
    // In old abi, or when weak symbols are not supported, there can
    // be multiple instances of a type_info object for one
    // type. Uniqueness must use the _name value, not object address.
    bool before(const type_info& __arg) const _GLIBCXX_NOEXCEPT;
    bool operator==(const type_info& __arg) const _GLIBCXX_NOEXCEPT;

however, I can get to this only next week, I'm traveling now, thus, if you
like, feel free to revert for now my commit and close this bug.
