It's a bug in select(), and is still present in blead. Looks like select() isn't calling get magic on the timeout arg.
Here's another example of using a magic var which fails
unless its magic value has been previously retrieved
(using the commented-out line):
"5" =~ /(\d)/;
#$x = $1;
select (undef, undef, undef, $1);
You may want to perlbug this.
Dave.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
