<p>This annotation occurs right before <small>GDB</small> responds to an error.
</p>
<p>Quit and error annotations indicate that any annotations which <small>GDB</small> was
in the middle of may end abruptly. For example, if a
<code>value-history-begin</code> annotation is followed by a <code>error</code>, one
cannot expect to receive the matching <code>value-history-end</code>. One
cannot expect not to receive it either, however; an error annotation
does not necessarily mean that <small>GDB</small> is immediately returning all the way
to the top level.

<a name="index-error_002dbegin-annotation"></a>
<p>A quit or error annotation may be preceded by
</p>
<div class="smallexample">
<pre class="smallexample">^Z^Zerror-begin
</pre></div>
<p>Any output between that and the quit or error annotation is the error
message.
</p>
<p>Warning messages are not yet annotated.
