1881. Standard-layout classes and unnamed bit-fields

Section: Clause 11  [class]     Status: CD4     Submitter: Dinka Ranns     Date: 2014-02-25

[Moved to DR at the November, 2014 meeting.]

According to 11.4.10 [class.bit] paragraph 2,

Unnamed bit-fields are not members and cannot be initialized.

However, the rules defining standard-layout classes in Clause 11 [class] paragraph 7 do not account for the fact that a class containing an unnamed bit-field has associated storage.

See also issue 1813 for a related question about standard-layout classes.

Proposed resolution (June, 2014):

This issue is resolved by the resolution of issue 1813.
