Seems we've a leak here: $ php -f 14582.php NULL object(cinput_select)(3) { ["values"]=> array(0) { } ["name"]=> &array(0) { } ["options"]=> &array(0) { } } ./zend_execute.c(425) : Freeing 0x082FC964 (2 bytes), script=14582.php zend_variables.c(107) : Actual location (location was relayed) I remember seeing another BR leeking at the same place when trying to access arrays with constants but can't find it right now. Previous Comments: ------------------------------------------------------------------------ [2001-12-18 11:11:07] [EMAIL PROTECTED] I've encountered stack problem. Here is simplest code, that reproduces this: <?php class CForm { var $inputs; function Cform() { $this -> inputs = array(); } function &get_input($name) { return($this -> inputs[$name]); } }; class Cinput_select { var $values; var $name; function Cinput_select($t) { $this -> name = $t; $this -> options = array(); } function add_value($value) { $this -> values[] = $value; } }; $form = new CForm(); //coment next two lines and new returns NULL $sel = new CInput_select("b"); $sel -> add_value("a"); $a =& $form -> get_input("a"); var_dump($a); $sel = new CInput_select("test"); var_dump($sel); $sel -> add_value("a"); ?> After call to CForm::get_input() $a is not a registered variable. Later new returns corrupted structure. If you comment out first two lines of program new returns NULL. In my original source code even when I created object using diffrient name after assigning NULL reference to variable new still corupts some of my variables. I think its becouse $a doesn't have storage on stack but interpreter thinks that it has. I think that returning NULL reference should initialize variable to false. This is code is not good programming pracitce and could be easily ommited, but taht doesn't change the fact that this is a bug. regards Lukasz Michalski ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=14582&edit=1 -- PHP Development Mailing List <http://www.php.net/> To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
