Bug description:Crash on __call + __invoke magic
Description:
------------
Using PHP versions 5.3.3 up to 5.3.10:
A 'container' has many 'bags', but few methods. Each 'bag' has its own
methods that are callable through it's magic __invoke method. No methods
collide with the properties of the 'container', so one would expect that:
bag_container->bagone('e', array('Some Text'))
Would trigger bag_container's __call (since no method 'bagone' exists in
'bag_container'), which would further trigger the __invoke method in class
'bag'.
Unfortunately, it just creates a segfault =|
I see that there is a related bug
(https://bugs.php.net/bug.php?id=53195&edit=2), but since the bug has not
been updated and this one produces different behavior (segfault), I felt
that I should resubmit. Apologies if that's wrong.
Test script:
---------------
class bag {
public function e($something) {
echo $something;
}
public function __invoke() {
return call_user_func_array(array($this, $method), $args);
}
}
class bag_container {
public $bagone;
public function __construct() {
$this->bagone = new bag();
}
public function __call($method, array $args = array()) {
return call_user_func_array(array($this, $method), $args);
}
}
$c = new bag_container();
$c->bagone('e', array('wtf'));
Expected result:
----------------
One would expect 'wtf' to be echo'd.
Actual result:
--------------
Segmentation fault.
