Hi all,

I've just upgraded my server to PHP 5.2.1, and roundcube stopped working 
, here is what I get every time I access the directory root:

[15-Feb-2007 14:10:03] PHP Warning:  preg_split() [<a 
href='function.preg-split'>function.preg-split</a>]: Compilation failed: 
lookbehind assertion is not fixed length at offset 7 in 
/usr/local/www/roundcube/program/lib/DB/common.php on line 751
[15-Feb-2007 14:10:03] PHP Warning:  Invalid argument supplied for 
foreach() in /usr/local/www/roundcube/program/lib/DB/common.php on line 756
[15-Feb-2007 14:10:03 +0400] DB Error: DB Error: mismatch Query:  [DB 
Error: mismatch] in 
/usr/local/www/roundcube/program/include/rcube_db.inc on line 501
[15-Feb-2007 14:10:03] PHP Fatal error:  Call to a member function 
fetchRow() on a non-object in 
/usr/local/www/roundcube/program/include/rcube_db.inc on line 368


Looking at /usr/local/www/roundcube/program/lib/DB/common.php:751 seems 
this preg_split is causing the error:

     function prepare($query)
     {
         $tokens   = preg_split('/((?<!\\\)[&?!])/', $query, -1,
                                PREG_SPLIT_DELIM_CAPTURE);
[snip]

Everything worked with PHP 5.2.0... So either something wrong with 
5.2.1, or that regexp is invalid... Googling around found this related 
bug: http://bugs.php.net/bug.php?id=38327&edit=1


Any ideas?
Vahan
