title: A Python Exception error in gdb 7.10
body: <p>I have installed <code>gdb 7.10</code> under <code>Ubuntu 14.04</code> by compiling from the source as detailed in <a href="https://askubuntu.com/a/529795/111162">this</a> answer (with the only exception that I copied the executable into <code>/usr/bin</code>). When I execute commands in <code>gdb</code>, I get the following error:</p>
  
  <pre><code>Python Exception &lt;type 'exceptions.NameError'&gt; Installation error: gdb.execute_unwinders function is missing: 
  </code></pre>
  
  <p>What can I do to get rid of it?</p>
