Bug ID: 65165 Summary: missing std::promise::set_value_at_thread_exit Product: gcc Version: 4.9.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: carlo at gcc dot gnu.org Assuming en.cppreference.com is right, this member function should exist since C++11. See http://en.cppreference.com/w/cpp/thread/promise/set_value_at_thread_exit It exists/works in clang 3.5. I see no reference to this function anywhere on gnu.org (ie, the status page), so I thought it might be something that has been overlooked.
