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.
This code does infact cause a crash (not limited to Win32). However,
the crash is the result of a bug in the PCRE library, please report it
to the authors of said library. This is not a PHP bug.

What is the XML file used?
------------------------------------------------------------------------
[2003-10-21 06:15:42] dcahh at gmx dot de
Description:
------------
I tried to parse a .xml-file using the regular expression as below.
Using the s modifier reproduces a crash, leaving it away the crash does
not appear.
System message:
The exception "unkown software expection" (0xc00000fd) occured in the
program at 0x00c3912d. OK / Cancel
(translated from German error message)
Reproduce code:
---------------
preg_match_all('~<(\w+)/?>(.)*</(\1)>~sm', $this->sFile, $aTags); //
havin s modifier reproduces the crash, leaving it away = no crash
Expected result:
----------------
Regular Expression matches
