Bug #38217 ReflectionClass::newInstanceArgs() tries to allocate too much memory
Submitted: 2006-07-26 07:46 UTC Modified: 2006-07-26 08:03 UTC

Status: Closed Package: Reproducible crash

Description:
------------
ReflectionClass::newInstanceArgs() tries to allocate huge pieces of memory, the engine dies because allowed memory size is exceeded.

Omitting the empty constructor makes the problem go away, so it might be related to that.

The error also occurs in PHP 5.1.4.

Reproduce code:
---------------
<?php
  class Object {
    public function __construct() {
    }
  }
  
  $class= new ReflectionClass('Object');
  var_dump($class->newInstanceArgs());
?>


Expected result:
----------------
PHP Warning:  ReflectionClass::newInstanceArgs() expects exactly 2 parameters, 1 given in /usr/home/alex/reflection_newinstance.php
object(Object)#2 (0) {
}


Actual result:
--------------
PHP Fatal error:  Allowed memory size of 8388608 bytes exhausted (tried to allocate 550152752 bytes) in /usr/home/alex/reflection_newinstance.php on line 8
