1528. Repeated cv-qualifiers in declarators

Section: 9.3  [dcl.decl]     Status: CD3     Submitter: Richard Smith     Date: 2012-07-23

[Moved to DR at the April, 2013 meeting.]

There is no restriction against repeated cv-qualifiers in declarators, although there is (in 9.2.9 [dcl.type] paragraph 2) for those appearing in a decl-specifier-seq. However, most or all current implementations reject such code. Is a change needed?

Proposed resolution (October, 2012):

Change 9.2.9.2 [dcl.type.cv] paragraph 1 as follows:

There are two cv-qualifiers, const and volatile. Each cv-qualifier shall appear at most once in a cv-qualifier-seq. If a cv-qualifier appears in a decl-specifier-seq, the init-declarator-list of the declaration shall not be empty. [Note:...
