<p>Comment (by Roland Haas):</p>
<p>Changing from <code>charater*8</code> to <code>logical*8</code> may not be not be enough to avoid assignment. The intel compiler (ifort (IFORT) 18.0.3 <a href="https://bitbucket.org/einsteintoolkit/tickets/commits/20180410" rel="nofollow" class="ap-connect-link">20180410</a>) compiles this without warning:</p>
<div class="codehilite language-fortran"><pre><span></span><span class="k">program </span><span class="n">foo</span>
<span class="k">implicit none</span>
<span class="k"> </span><span class="kt">logical</span><span class="o">*</span><span class="mi">8</span> <span class="kd">::</span> <span class="n">bar</span>
<span class="kt">integer</span><span class="o">*</span><span class="mi">4</span> <span class="kd">::</span> <span class="n">baz</span>
<span class="n">bar</span> <span class="o">=</span> <span class="n">baz</span>
<span class="k">end program</span>
</pre></div>
<p>On the other hand we are not worried about assignment to the pointer itself. We want to fails is things like: <code>bar(1,2,3)</code> for reading and writing and passing <code>bar</code> to a subroutine (which we likely cannot prevent no matter what).</p>
<p>So it should be enough for our purposes.</p>
