The backtrace is _very_ long. Here is the first part:

Description:
------------
Although other regexps work fine; this one crashes since 4.4.7 is
installed
Reproduce code:
---------------
<?PHP
$x = new x();
class x {
function y($matches){
echo 'no problem!';
}
function x(){
preg_replace_callback('~\{([a-zA-Z\-_]{0,50})@([a-zA-Z_\d]{1,50})\}((?:(?:\{[a-zA-Z.\-_\d]{1,50}\}|[^\{\}]*)(\{,\})?)*)\{\1/\}~sU',
array(&$this, 'y'), '[EMAIL PROTECTED]/}');
}
}
?>
Expected result:
----------------
I would expect the x::y function to be ran by preg_replace_callback
Actual result:
--------------
[Sun May 06 20:47:49 2007] [notice] child pid 26044 exit signal
Segmentation fault (11)
