<p>Comment (by Roland Haas):</p>
<p>This is the sympton caused by using an outdated stdc++ template <a data-is-external-link="true" href="http://library.In" rel="nofollow">library. In</a> you fix you are basically re-introducing the compatibility hacks (more or less) that we have just removed from Cactus. A better fix for the compilation failure is to make sure that icpc uses a new enough g++ (and its STL library) by passing a <code>-gxx-name</code> option and the path to a new enough g++.</p>
<p>If on the other hand you really want an isnan that persists even when -Ofast is used (though you are defeating the Ofast purpose in that case and with Ofast there just may not be any NaN produce in a consitent way to begin with) you could use your change. But it addresses a different issue than the compilation failure I think.</p>
