[Paolo Carlini]

Hi Chris,

and thanks for investigating this issue well beyond the unique_ptr work proper.

I say you are right and a PR should be filed mentioning also, as a related, but indeed not identical issue (it's already fixed in mainline), middle-end/35593. Can you do that? If you can please add me and Richard Gunther in CC, otherwise, please let me know ASAP and I will.

Many thanks again,
Paolo.
