Same result for a fresh php5.2-200608261230 build.
I don't know, whether this helps, but in this build I interrupted the
process after about 10 seconds; here's the bt:

Description:
------------
When executing the code below, the function won't return but loop
forever (or do something else, I don't know).
Reproduce code:
---------------
<?php
$foo = 'bla bla bla';
preg_match('/(?<!\w)(0x[\p{N}]+[lL]?|[\p{Nd}]+(e[\p{Nd}]*)?[lLdDfF]?)(?!\w)/',
$foo);
?>
Expected result:
----------------
Something like that:
[EMAIL PROTECTED] ~ $ time perl -e '$_="bla bla bla";
/(?<!\w)(0x[\p{N}]+[lL]?|[\p{Nd}]+(e[\p{Nd}]*)?[lLdDfF]?)(?!\w)/;'
real 0m0.017s
user 0m0.016s
sys 0m0.000s
Actual result:
--------------
[EMAIL PROTECTED] ~ $ php
<?php
set_time_limit(10);
$foo = 'bla bla bla';
preg_match('/(?<!\w)(0x[\p{N}]+[lL]?|[\p{Nd}]+(e[\p{Nd}]*)?[lLdDfF]?)(?!\w)/',
$foo);
?>
Fatal error: Maximum execution time of 10 seconds exceeded in
/home/pberndt/- on line 4
