Boost C++ Libraries: Ticket #11515: dynamic_bitset move constructor should be conditionally noexcept https://svn.boost.org/trac10/ticket/11515 <p> It should be noexcept if buffer_type is nothrow move constructible, i.e., <code>noexcept(is_nothrow_move_constructible&lt;buffer_type&gt;::value)</code>. </p> <p> Otherwise, a <code>std::vector&lt;dynamic_bitset&gt;</code> will be forced to copy on reallocation. </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/11515 Trac 1.4.3
