if you declare more than one class in a file,and place 'die();' as the final excutable statement,PHP will crash....

e.g:
<?php 
class T{
	var $q;
	function W(){
		echo 'Q';
	}
}

ob_start();
show_source(__FILE__);
$result=ob_get_contents();
ob_end_clean();
$a=false;
if ($a=='1'):
	echo 'Hi';
endif;
while(false){
	echo 'No';
}
$result=str_replace ("<br>", "\n", $result);
echo '<pre>'.strip_tags($result,'<font>').'</pre>';
die('');
class V{
	var $q;
	function W(){
		echo 'Q';
	}
}
?>
will make PHP crash,but
<?php 
/*

class T{
	var $q;
	function W(){
		echo 'Q';
	}
}

ob_start();
show_source(__FILE__);
$result=ob_get_contents();
ob_end_clean();
$a=false;
if ($a=='1'):
	echo 'Hi';
endif;
while(false){
	echo 'No';
}
$result=str_replace ("<br>", "\n", $result);
echo '<pre>'.strip_tags($result,'<font>').'</pre>';
die('');
;//if you add a executable statement here, it will be fine.
class V{
	var $q;
	function W(){
		echo 'Q';
	}
}
?>
is fine.
