[jira] Updated: (STDCXX-306) std::gslice copy assignment
inaccessible
[ 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.
