https://svn.boost.org/trac10/ticket/12717 <p> <code>boost::lockfree::queue::queue(void)</code> can only be called if if <code>boost::lockfree::capacity</code> was specified (as enforced by the <code>BOOST_ASSERT</code> in include/boost/lockfree/queue.hpp line 179. However this requirement is not enforced in a non-debug build and it is not mentioned in the documentation for <code>boost::lockfree::queue::queue(void)</code>. </p> <p> The same thing is true of <code>boost::lockfree::queue::queue(allocator const &amp;)</code> in include/boost/lockfree/queue.hpp line 198 and of <code>boost::lockfree::queue::queue(size_type)</code> in include/boost/lockfree/queue.hpp line 210. </p> <p> I think these restrictions should be included in the documentation. The docs would lead me to believe that one could write </p> <pre class="wiki">void some_function() { boost::lockfree::queue&lt;int&gt; q; } </pre><p> But if that is built in debug mode it will fail the assertion in include/boost/lockfree/queue.hpp line 179 </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/12717 Trac 1.4.3
