Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID --- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> 2013-04-09 12:26:18 UTC --- As Daniel says, you're missing a default constructor. And if you define the type as non-copyable then obviously you can't copy it. This is not a GCC bug.
