<p>This declaration in <code>cctki_GroupsOnGH.h</code> is wrong; it should not have the <code>pure</code> attribute:</p>
<div class="codehilite language-c"><pre><span></span><span class="kt">void</span> <span class="o">*</span><span class="nf">CCTKi_VarDataPtrI</span><span class="p">(</span><span class="k">const</span> <span class="n">cGH</span> <span class="o">*</span><span class="n">GH</span><span class="p">,</span> <span class="kt">int</span> <span class="n">timelevel</span><span class="p">,</span> <span class="kt">int</span> <span class="n">varindex</span><span class="p">)</span> <span class="n">CCTK_ATTRIBUTE_PURE</span><span class="p">;</span>
</pre></div>
<p>This function checks whether the caller has access to that grid variable and returns <code>NULL</code> if not. It does not always return the same pointer.</p>
<p>Also, the variable pointer changes over time if the driver reallocates storage.</p>
