 ]

Martin Sebor closed STDCXX-171.
-------------------------------

       Resolution: Invalid
    Fix Version/s:     (was: 4.2.2)

As Farid says, the test case is invalid due to LWG issue #[538 | 
http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#538].

> [LWG #538] std::unique_copy() requires CopyConstructible and Assignable
> -----------------------------------------------------------------------

>                 Key: STDCXX-171
>                 URL: https://issues.apache.org/jira/browse/STDCXX-171
>             Project: C++ Standard Library
>          Issue Type: Bug
>          Components: 25. Algorithms
>    Affects Versions: 4.1.3
>         Environment: all
>            Reporter: Anton Pevtsov
>            Priority: Minor
>   Original Estimate: 2h
>  Remaining Estimate: 2h
>
> The following test fails to compile:
> #include <algorithm>
> #include <iterator>
> #include <iostream>
> struct no_assign {
>     int const x;
>     no_assign() : x(23) { }
>     operator int() const { return x; }
> };
>  // this program should output a single "23".
> int main()
> {
>     no_assign in[4];
>     std::unique_copy(in, in+4, std::ostream_iterator<int>(std::cout, "\n"));
> }
> The unique_copy standard requirements are still discussed:
