Thanks for reporting this issue Adam. Don't hesitate to file bug reports in gcc bugzilla category libstdc++ when you find problems like this in the future!

Yes please. Thanks for the quickness on this Jakub. For the record, I just did an audit of src/*inst.cc files mapped to include files with non-operator && usage to look for similar issues in other classes. (Non-exported symbols required for move semantics to function in other library areas.) I didn't find any. best, benjamin
