Further testing shows that ereg_replace throws an error on the
particular regex while mb_ereg_replace does not.

I have since upgraded to PHP 5.2.1.
I've isolated this bug to a specific function, an example script is
shown here:
<?php
$test = 'afds [EMAIL PROTECTED] sfda';
echo $test.'<br>';
$test = mb_ereg_replace('\#([^,]+?)\@(irc(\.[\w\-]+)+)','<a class="irc"
href="irc://\2/\1">[EMAIL PROTECTED]</a>', $test);
echo $test;
?>
the intended use for this code segment is to replace irc links in text
with clickable ones, eg, "[EMAIL PROTECTED]" becomes "<a
href="irc://irc.freenode.net/blah">[EMAIL PROTECTED]</a>
Crashes can be reproduced with ab (ApacheBench) with the following
command line:
ab -n 1000 -c 50 http://url/
Crashes occur faster when concurrency is higher, at -c 2 or so crashes
don't happen.
Workaround:
Replacing mb_ereg_replace with ereg_replace stops the crashing from
occuring, but with loss of multibyte support.

Unfortunatelly we are not able to generate debug pack for PHP4. You
would have to come up with reproducing script the old fashioned, trial
and error way :)

Can a PHP 4.4.4 Win32 debug pack be created? I'm having a very
difficult time isolating the script for this problem.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
