<sect1><heading>Debugging a crash dump with DDD</heading>
<p>Examining a kernel crash dump with a graphical debugger like
<tt>ddd</tt> is also possible. Add the option <tt>-k</tt> to
the <tt>ddd</tt> command line you would use normally. For example:
<tscreen><verb>
ddd -k /var/crash/kernel.0 /var/crash/vmcore.0
</verb></tscreen>
You should then be able to go about looking at the crash dump
using <tt>DDD</tt>'s graphical interface.
