@cataphract it's a knew segfault, that is the call stack exceeded. so I think
it's
okey to close it.

If it segfaults, there's still a bug. Please don't close it.

I suppose I did =) I don't see how I missed that (I chopped down my code as I
am obviously not working with bags).
I don't see why this would cause a segfault instead of issuing a
failure/warning notice, but that works =) Thank you!

do you mean like this:
<?php
class bag {
public function e($something) {
print_r($something);
}
public function __invoke($args) {
return call_user_func_array(array($this, array_shift($args)), $args);
}
}
class bag_container {
public $bagone;
public function __construct() {
$this->bagone = new bag();
}
public function __call($method, array $args = array()) {
$this->bagone->__invoke($args);
}
}
$c = new bag_container();
$c->bagone('e', array('wtf'));

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.
