<p>If you use the gcc python plugin to improve your code, we’d love to hear about
it.</p>
<p>If you want to share a success story here, please email the plugin’s <a class="reference external" href="https://fedorahosted.org/mailman/listinfo/gcc-python-plugin/">mailing list</a>.</p>

<p>Tom Tromey also wrote specialized Python scripts to use the GCC plugin to
locate bugs within GDB.</p>
<p>One of his scripts analyzes gdb’s resource-management code, which found some
resource leaks and a possible crasher:</p>
<blockquote>
<div><ul class="simple">
<li><a class="reference external" href="http://sourceware.org/ml/gdb-patches/2011-06/msg00408.html">http://sourceware.org/ml/gdb-patches/2011-06/msg00408.html</a></li>
</ul>
</div></blockquote>
<p>The other generates a whole-program call-graph, annotated with information
on gdb’s own exception-handling mechanism. A script then finds places where
these exceptions were not properly integrated with gdb’s embedded Python
support:</p>
