</div><h4>Requirements:</h4>
<p>E must be boost::<span class="RenoLink"><a href="exception.html">exception</a></span>, or a type that derives (indirectly) from boost::<span class="RenoLink"><a href="exception.html">exception</a></span>.</p>
<h4>Postcondition:</h4>
<p>A copy of v is stored into x. If x already contains data of type <span class="RenoLink"><a href="error_info.html">error_info</a></span>&lt;Tag,T&gt;, that data is overwritten. Basic exception safety guarantee.</p>
<h4>Returns:</h4>
<p>x.</p>
<div class="RenoIncludeDIV"><h4>Throws:</h4>
<p>std::bad_alloc, or any exception emitted by the T copy constructor.</p>
