https://svn.boost.org/trac10/ticket/10546 <p> I am unable to build a simple project using boost coroutine on machines using gcc 4.4.7 (centos6.4, redhat 6.0, 6.1, etc). The same project builds fine using machines running gcc 4.8.3 (fedora 19, centos 7.0). </p> <p> Since the <a href="http://www.boost.org/users/history/version_1_55_0.html">Boost 1.55 version history</a> does list gcc 4.4.7 as a tested compiler, this likely means a regression. </p> <p> The simple test file consists of the following main.cpp file: </p> <pre class="wiki">#include &lt;iostream&gt;
