title: Valgrind unhandled instruction bytes error
body: <p>In order to search for memory leaks in my application based on the Liv555 library, I tried to run it using valgrind. It results in the following error:</p>
  
  <pre><code>vex amd64-&gt;IR: unhandled instruction bytes: 0xC5 0xF9 0x57 0xC0 0xC5 0xFA 0x10 0x15
  </code></pre>
  
  <p>Running it on another computer does not result in this error (it runs just fine), so I expect this to be the result of some library version. Could this be the problem? If so, does anyone know which library could be causing the error? 
  The output of <code>valgrind</code> with the <code>-v -v</code> options is located <a href="http://www.tym.nl/valgrind_output.txt" rel="noreferrer">here</a>.</p>
