Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |WONTFIX --- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> --- LWG consensus was that the breakage is OK for C++17, and there was no desire to support this code even for C++11 and C++14 modes. So I'm closing this as WONTFIX.
