I can't replicate on Linux/Ubuntu 8.04 with 5.3CVS or 5.2.*

When I increase the number of patterns to a large number (say 60000) I
get a suitable warning:

Warning: preg_match(): Compilation failed: too many named subpatterns
(maximum 10000) at offset 148903 in
/home/martin/php_bugs/pcre/47622/test.php on line 10

for($bar=0; $bar<64; $bar++) {
	$regex .= '((?P<foo'.$bar.'>))';

$regex .= '@';
 
preg_match($regex, 'foobar');

?>

Nothing
