Boost C++ Libraries: Ticket #13161: Optional vector assignment regression https://svn.boost.org/trac10/ticket/13161 <pre class="wiki">boost::optional&lt;std::vector&lt;int&gt;&gt; v; v = { 1, 3 }; </pre><p> Assignment doesn't compile anymore. It worked in 1.62 and reports an error in 1.63. I think it has to do with the addition of BOOST_NO_CXX11_UNIFIED_INITIALIZATION_SYNTAX but I could be wrong. </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/13161 Trac 1.4.3 anonymous Wed, 16 Aug 2017 03:39:04 GMT component changed; owner set https://svn.boost.org/trac10/ticket/13161#comment:1 https://svn.boost.org/trac10/ticket/13161#comment:1 <ul> <li><strong>owner</strong> set to <span class="trac-author">Fernando Cacciola</span> </li> <li><strong>component</strong> <span class="trac-field-old">None</span> → <span class="trac-field-new">optional</span> </li> </ul> Ticket
