<h3 class="section">6.1 Have You Found a Bug?</h3>
<p><a name="index-bug-criteria-640"></a>
If you are not sure whether you have found a bug, here are some guidelines:
<a name="index-fatal-signal-641"></a>
<a name="index-linker-crash-642"></a>
<a name="index-crash-of-linker-643"></a>
<ul><li>If the linker gets a fatal signal, for any input whatever, that is a
<span class="command">ld</span> bug. Reliable linkers never crash.
<p><a name="index-error-on-valid-input-644"></a><li>If <span class="command">ld</span> produces an error message for valid input, that is a bug.
<p><a name="index-invalid-input-645"></a><li>If <span class="command">ld</span> does not produce an error message for invalid input, that
may be a bug. In the general case, the linker can not verify that
object files are correct.
<li>If you are an experienced user of linkers, your suggestions for
improvement of <span class="command">ld</span> are welcome in any case.
</ul>
