<h3 class="section">31.1 Have You Found a Bug?</h3>
<a name="index-bug-criteria"></a>
<p>If you are not sure whether you have found a bug, here are some guidelines:
</p>
<ul>
<li> <a name="index-fatal-signal"></a>
<a name="index-debugger-crash"></a>
<a name="index-crash-of-debugger"></a>
If the debugger gets a fatal signal, for any input whatever, that is a
<small>GDB</small> bug. Reliable debuggers never crash.
</li><li> <a name="index-error-on-valid-input"></a>
If <small>GDB</small> produces an error message for valid input, that is a
bug. (Note that if you’re cross debugging, the problem may also be
somewhere in the connection to the target.)
</li><li> <a name="index-invalid-input"></a>
If <small>GDB</small> does not produce an error message for invalid input,
that is a bug. However, you should note that your idea of
“invalid input” might be our idea of “an extension” or “support
for traditional practice”.
</li><li> If you are an experienced user of debugging tools, your suggestions
for improvement of <small>GDB</small> are welcome in any case.
</li></ul>
