New Comment:
This test case must not work at all.
$ php -d "zend.ze1_compatibility_mode=1" bug34712.php
Fatal error: Cannot use 'parent' as class name as it is reserved in
/home/dmitry/php/test/bug34712.php on line 20
Without "parent" it works fine on Linux/i386.
Try to make full rebuild.

last two lines of sample code should be:
$c = new child;
$a = new aggrevator($c);

Description:
------------
segfault in solaris 10, using php-5.0.6-dev - php5-STABLE-200510030637
Program received signal SIGSEGV, Segmentation fault.

Reproduce code:
---------------
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
