Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |FIXED --- Comment #23 from Jonathan Wakely <redi at gcc dot gnu.org> --- I think we can close this. The concrete issue of the pair(pair&&) move constructor was fixed years ago as PR 53657, and I'm not aware of any more incompatibilities in recent releases (where C++11 support is stable, and so should be ABI compatible with C++98). Any other incompatibilities are bugs and will be fixed if reported.
