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

Date: 2011-02-15.00:00:00

Proposed resolution (February, 2011) [SUPERSEDED]:

Change 9.12.2 [dcl.align] paragraph 5 as follows:

The combined effect of all alignment-specifiers in a declaration shall not specify an alignment that is less strict than the alignment that would otherwise be required for the entity being declared if all alignment-specifiers were ignored (including those in other declarations).

According to 9.12.2 [dcl.align] paragraph 5,

The combined effect of all alignment attributes in a declaration shall not specify an alignment that is less strict than the alignment that would otherwise be required for the entity being declared.

“...would otherwise be required” could be read as referring to the alignment set by another declaration of the entity. However, it was intended to prevent specifying an alignment smaller than the natural alignment the entity would have in the absence of an align attribute. The wording should be changed to make that clearer.
