<p>The Debugger is an application the common user hasn't much use for. It's targetted at developers to investigate bugs in programs. Sometimes those bugs result in crashes and that is where even end users come into contact with the Debugger. When a program crashes, you're confronted with this alert:</p>
<p>It gives three options to react to the crash:</p>
<ul>
<li><p><spanclass="button">Terminate</span> will clean up after the crashed app but otherwise does nothing further.</p></li>
<li><p><spanclass="button">Debug</span> will start the Debugger for further investigation.</p></li>
<li><p><spanclass="button">Save report</span> creates a debug report which is saved as a text file on the Desktop and can be emailed to the developer of the crashed app or attached to a ticket at its bugtracker, if available.<br/>
The debug report contains information on your hardware (type of CPU and used memory etc.), the exact version of Haiku and all available information on the state of the system that could be relevant to the crash.</p></li>
</ul>
<p>Describing the usage of the actual Debugger is out of scope for this guide that is addressing the needs of the common user of Haiku. For completeness sake, here's the window that'll come up if you choose the <spanclass="button">Debug</span> option in the above alert:</p>
<p>As you'll quickly see when you start poking around a bit, the Debugger is one of the most complex and sophisticated applications for Haiku. If you're a developer and are used to graphical debuggers on other platforms, many features will be familiar to you.</p>
<p>As there's not a single document explaining the intricacies of Haiku's Debugger, below are a few links that may shed some light. If you have a specific question, you may want to consider posting it on the <ahref="http://www.freelists.org/list/haiku-development">development mailing list</a>. If you find more useful resources, please file a <ahref="../../../welcome/en/bugreports.html">bugreport</a> with that info.</p>
