--- Comment #18 from Martin Sebor <msebor at gcc dot gnu.org> --- The link works for me. An older version of the paper is here: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3396.htm If that doesn't work for you either try searching for the paper titled Dynamic memory allocation for over-aligned data by Clark Nelson.
