Subject [jira] Updated: (STDCXX-306) std::gslice copy assignment inaccessible
Date Mon, 15 Oct 2007 00:21:50 GMT

     [ https://issues.apache.org/jira/browse/STDCXX-306?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Martin Sebor updated STDCXX-306:
--------------------------------

         Severity: Compiler Error
    Fix Version/s:     (was: 4.2)
                   4.2.1
          Summary: std::gslice copy assignment inaccessible  (was: required std::gslice::operator=()
declared private)

As in the case of STDCXX-311, there is a question of the intended semantics of the copy assignment
operator (see also http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#621). Deferred
until 4.2.1 or until it's been made more clear what the intended semantics should be.
