Some of the examples are broken because they use C++ language constructs but they&#x27;re being compiled as C code, which leads to error messages like:<p><pre><code>  13 : error: &#x27;static_cast&#x27; undeclared (first use in this function)
     input = static_cast&lt;int*&gt;(__builtin_assume_aligned(input, 64));
             ^</code></pre>
