Jan Kratochvil <jan.kratochvil at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Version|6.0 |5.1.1 Resolution|--- |INVALID --- Comment #1 from Jan Kratochvil <jan.kratochvil at redhat dot com> --- PASS: gcc-5.1.1-1.fc22.x86_64 FAIL: gcc-4.9.2-6.fc21.x86_64 It is in fact already fixed thanks to Python xmethods. The option would still make some sense for custom non-libstdc++ templates if one does not write xmethods for them but that has probably only marginal usefulness.
