https://svn.boost.org/trac10/ticket/9689 <p> C++11 introduces std::piecewise_construct, which is needed in some scenarios; for instance, to emplace a default-initialized object into a container. </p> <p> boost::unordered already allows it (<a href="http://www.boost.org/doc/libs/1_55_0/doc/html/unordered/compliance.html">http://www.boost.org/doc/libs/1_55_0/doc/html/unordered/compliance.html</a>), but boost::container doesn't. </p> <p> This question on <a class="missing wiki">StackOverflow</a> illustrates this further: <a class="ext-link" href="http://stackoverflow.com/questions/21438244/"><span class="icon">​</span>http://stackoverflow.com/questions/21438244/</a> </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/9689 Trac 1.4.3 Ion Gaztañaga Tue, 23 Aug 2016 21:16:04 GMT https://svn.boost.org/trac10/ticket/9689#comment:1 https://svn.boost.org/trac10/ticket/9689#comment:1 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> <p> Reviewing old bugs. piecewise_construct support was added in commit: </p> <p> <a class="ext-link" href="https://github.com/boostorg/container/commit/79a75f470e75f35f5f2a91e10fcc67d03b0a2160"><span class="icon">​</span>https://github.com/boostorg/container/commit/79a75f470e75f35f5f2a91e10fcc67d03b0a2160</a> </p> <p> Which should be available in Boost 1.62.
