<p>SummationByParts sets <code>ni = cctk_lsh[0]</code> but then uses this (in Fortran code) to size the array in memory:</p>
<div class="codehilite language-fortran"><pre><span></span><span class="n">CCTK_REAL</span><span class="p">,</span> <span class="k">dimension</span><span class="p">(</span><span class="n">ni</span><span class="p">,</span><span class="n">nj</span><span class="p">,</span><span class="n">nk</span><span class="p">),</span> <span class="k">intent</span><span class="p">(</span><span class="n">IN</span><span class="p">)</span> <span class="kd">::</span> <span class="n">var</span>
</pre></div>
<p>which will fail when <code>cctk_lsh != cctk_ash</code> that is when padding is used.</p>
