can't exactly pin down reproduceable code, but it seems to be something
similar to the following:
class aggrevator {
function aggrevator(&$obj) {
$this->obj = &$obj;
$this->_call();
}
function _call()
{
$this->obj->callback();
}
}
class helper {
function helper(&$obj)
{
$this->obj_ref = &$obj;
}
}
class parent { }
class child extends parent {
function callback() {
$this->_helper = new helper($this);
}
}
$c = new child;
$h = new helper($c);
Expected result:
----------------
not to crash...
Actual result:
--------------
f'd in the a, segfault
