Thank you for the advice. As a rule, I use the following in my CGI:
use strict;
use warnings;
use diagnostics;
...
In httpd.conf, I use:
PerlTaintCheck On
PerlModule Apache::DBI
PerlModule Apache::StatINC
...
<Files ~ "\.pl$">
SetHandler perl-script
PerlHandler Apache::Registry
PerlSendHeader On
Options ExecCGI
</Files>
I've been running the script under -T -d also, at the shell, looking for
culprets. I've managed to cut it down into a smaller subset of functions,
no graphics, no CGI.pm-driven HTML, and the problem went away. Now I have
to start adding bits to see when it occurs again.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
