I didn't see that Jani reproduced this.
FWIW, I can not reproduce using current CVS or with
PHP 4.2.1 (the oldest version I had to hand just now)
using the short script that you provided.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
Could you supply a backtrace?
Also, could you try with a non-stable snapshot from the
last couple of days as the PCRE library was updated recently.

Tests of different lengths of string '$x' show that if
strlen($x) > 4040 the crash occurs i.e. with the last
text is 'Randomized-Controlled-Trial' php will crash. A
shorter script as requested is:
<?php
$x = '';
while (true) {
$x .= '*';
$len = strlen($x);
preg_match('/(.|[\r\n])+/', $x, $match);
echo "<br />$len\n";
}
?>

I can reproduce the crash on Linux too. But could you try
shortening the example script to something bit smaller?

By php version 4.3.1 I mean 4.2.1 of course ;-)
