Boost Exception In other libraries, watch for compile error referring to throw_exception_assert_compatibility in boost::throw_exception. Resolve by throwing an exception that derives from std::exception. This is not a new requirement but it is being enforced now.

</div><h4>Requirements:</h4>
<p>E must derive publicly from std::exception.</p>
<h4>Effects:</h4>
<div><ul><li> If BOOST_NO_EXCEPTIONS is not defined, boost::<span class="RenoLink"><a href="throw_exception.html">throw_exception</a></span>(e) is equivalent to throw boost::<span class="RenoLink"><a href="enable_current_exception.html">enable_current_exception</a></span>(boost::<span class="RenoLink"><a href="enable_error_info.html">enable_error_info</a></span>(e)), unless BOOST_EXCEPTION_DISABLE is defined, in which case boost::<span class="RenoLink"><a href="throw_exception.html">throw_exception</a></span>(e) is equivalent to throw e;</li>
<li> If BOOST_NO_EXCEPTIONS is defined, the function is left undefined, and the user is expected to supply an appropriate definition. Callers of throw_exception are allowed to assume that the function never returns; therefore, if the user-defined throw_exception returns, the behavior is undefined.</li>
