The r16-5845-g8a2e6590cc4a2f changed the _Safe_container copy-assignment
to delegate to assigment 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.
---
Turned out to be simple fix, but took me some time to realize what actually
caused the regressions.
Testing on x86_64-linux (on cfarm). *unordered_* tests all passed with
debug mode locally. OK for trunk?
