Richard Smith <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED CC| |[email protected] Resolution|--- |INVALID --- Comment #1 from Richard Smith <[email protected]> --- You've misunderstood how copy elision works. The program is analysed according to the normal language rules (including template instantiation etc), except that the implementation is permitted to choose to not perform a copy *if it feels like it*. The definition is still required, because the implementation could choose to invoke it. (And note that an implementation is not even required to make the same choice each time it takes the same path through the same code.) -- You are receiving this mail because: You are on the CC list for the bug.
