<p>Comment (by Roland Haas):</p>
<p>Here’s a configure test fragment to trigger the issue:</p>
<div class="codehilite language-c++"><pre><span></span><span class="cp">#include</span> <span class="cpf"><cmath></span><span class="cp"></span>
<span class="kt">void</span> <span class="nf">badmath</span><span class="p">(</span><span class="kt">void</span><span class="p">)</span>
<span class="p">{</span>
<span class="k">using</span> <span class="k">namespace</span> <span class="n">std</span><span class="p">;</span>
<span class="n">isnan</span><span class="p">(</span><span class="mf">0.</span><span class="p">);</span>
<span class="p">}</span>
</pre></div>
<p>to be compiled with <code>icpc -std=c++11 -gxx-name=g++ -O0 -c badmath.cc</code> or <code>g++ -std=c++11 -O0 -c badmath.cc</code>.</p>
