<P>[Voted into the WP at the March, 2011 meeting as part of paper N3262.]</P>

<P>Now that alignment can be applied directly to class types, the
current wording of the note at the end of 6.8.3 [<A href="https://wg21.link/basic.align#3">basic.align</A>] paragraph 3
is no longer correct:</P>

<BLOCKQUOTE>

[<I>Note:</I> every over-aligned type is or contains a class type with
a non-static data member to which an extended alignment has been
applied. &#8212;<I>end note</I>]

</BLOCKQUOTE>

<P><B>Proposed resolution (November, 2010) [SUPERSEDED]:</B></P>

<P>Change 6.8.3 [<A href="https://wg21.link/basic.align#3">basic.align</A>] paragraph 3 as follows:</P>

<BLOCKQUOTE>

[<I>Note:</I> every over-aligned type is <DEL>or contains</DEL> a
class type <DEL>with a non-static data member to which an
extended alignment has been applied</DEL> <INS>to which extended
alignment applies (possibly through a non-static data
member)</INS>. &#8212;<I>end note</I>]
