+				    <p>(Observed with valgrind 3.2.1, fixed in 3.2.3)<br/>
+Valgrind 3.2.1 sometimes produces supressions that don't work, like this:</p>
+<div class="code"><div class="codeContent">
+<pre class="code-java">{
+  &lt;insert a suppression name here&gt;
+  Memcheck:Free
+  fun:_vgrZU_libcZdsoZa_free
+  fun:main
+}</pre>
+</div></div>
+<p>The identifying characteristic is that they begin with fun:_vg&lt;something&gt;</p>
+
+<p><a href="http://article.gmane.org/gmane.comp.debugging.valgrind/5939" title="Visit page outside Confluence">http://article.gmane.org/gmane.comp.debugging.valgrind/5939</a> explains what these symbols are.</p>
+
+<p>The workaround is to replace fun:<em>vg*_lib*</em>&lt;something&gt; with fun:&lt;something&gt;, where something<br/>
+should be a valid C or C++ mangled symbol.</p>
+
+<p>The following test program demonstrates the problem</p>
+<div class="code"><div class="codeContent">
+<pre class="code-java">#include &lt;stdlib.h&gt;
+<span class="code-object">int</span> main(<span class="code-object">int</span> argc,<span class="code-object">char</span>**argv) {
+   <span class="code-object">char</span>*p = malloc(10);
+   free(p);
+   free(p);
+}</pre>
+</div></div>
