--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> --- Author: redi Date: Wed May 2 16:25:44 2018 New Revision: 259842 URL: https://gcc.gnu.org/viewcvs?rev=259842&root=gcc&view=rev Log: PR libstdc++/69608 Move semantics for strstreambuf In libstdc++ the deprecated char* streams are non-copyable, as was required pre-C++11. Since C++11 the standard implies that those streams should be copyable, but doesn't specify the effects of copying them. This is surely a defect, so for consistency with other implementations this change makes them movable, but not copyable. PR libstdc++/69608 * include/backward/strstream (strstreambuf): Define move constructor and move assignment operator. (istrstream, ostrstream, strstream): Likewise. * testsuite/backward/strstream_move.cc: New. Added: trunk/libstdc++-v3/testsuite/backward/strstream_move.cc Modified: trunk/libstdc++-v3/ChangeLog trunk/libstdc++-v3/include/backward/strstream
