Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Known to fail| | --- Comment #9 from Jonathan Wakely <redi at gcc dot gnu.org> --- We could add a deprecated attribute to the default ctor (or even make it private) for -pedantic or for -std=c++NN modes, but IMHO doing so is very very low priority. Some code compiles with one implementation and not with others. You have to deal with that.
