X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=56c6612598a07514a65ad5c0b25d12d1fc966e4c;p=thirdparty%2Fgcc.git libstdc++: Fix debug mode for unordered containers. The r16-5845-g8a2e6590cc4a2f changed the _Safe_container copy-assignment to delegate to assignment of the _Base. However, _Safe_unordered_container_base was not updated, and due the presence of move constructor, it's assignments are deleted, causing hard error for assignment of any unordered container. libstdc++-v3/ChangeLog: * include/debug/safe_unordered_base.h (_Safe_unordered_container_base::operator=): Define as defaulted, inherit behavior of _Safe_sequence_base.
