<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-crash"></a>
If a binary utility gets a fatal signal, for any input whatever, that is
a bug.  Reliable utilities never crash.

</li><li> <a name="index-error-on-valid-input"></a>
If a binary utility produces an error message for valid input, that is a
bug.

</li><li> If you are an experienced user of binary utilities, your suggestions for
improvement are welcome in any case.
</li></ul>
