The fixes regression from r16-5845-g8a2e6590cc4a2f that added an move
assignment operator to the _Safe_node_sequence, and made the class both
non move and copy constructible (copy is deleted, move is not declared).
In consequence debug version of node containers, that define they copy
and move as defaulted, and inherit from above, have deleted copy and moves.
libstdc++-v3/ChangeLog:
* include/debug/safe_sequence.h
(_Safe_node_sequence::_Safe_node_sequence): Define as defaulted.
---
This does not fix debug mode for unorderd containers (a lot of issue
there), but I think it sitll an improvment.
Testing on x86_64-linux. list, map, set seem to be fixed. OK for trunk?
