Thank you Andrei.
I installed the latest pcre lib version 4.5 and linked the php-4.3.4
against it, but the problem persisted.
Then I downloaded the latest snapshot of 4.3.5-dev and compiled it
using the bundled libpcre 4.5 and... problem solved :-)

Could not reproduce with the latest PCRE library version 4.5.

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.
Thank you for your interest in PHP.
I can verify the crash, however the crash is not the result of PHP code
but rather due to a bug in the pcre library. Please report this bug to
the maintainers of the pcre library.

Please provide sample of source text on which the regex operates.

Description:
php crashes when using the preg_match function. Code included below.
Works in php4.3.3RC1 but any later version causes segmentation fault.
The code is part of a text filter.
$output contains text with plain text and html mixed. The idea is
anything between [html] and [/html] will go untouched by the filter.
I use dozens of other regular expressions, but preg_match is a sure
killer. I can easily reproduce this behavior.
Reproduce code:
---
while (preg_match('/\[html]((.|\s)+?)\[\/html]/', $output, $htmlshow))
$output = str_replace($htmlshow[0], str_replace('', '',
strtr($htmlshow[1],
array_flip(get_html_translation_table(HTML_ENTITIES, $output);
Actual result:
--
child pid x exit signal Segmentation fault (11)
--
