Initializing $a->whatever before assigning reference can be used as a
temporary workaround.

Description:
------------
There is probably a bug in memory allocation related to property
getters. Note that the behavior depends on lengths of the two strings
and also on the way the $q property is initialized.
Reproduce code:
---------------
class A
{
var $q;
function __construct()
{
$this->q = array();
}
function __get($name)
{
return $this->q;
}
};
$a = new A;
$b = "short";
$a->whatever =& $b;
$b = "much longer";
var_dump($a);
Expected result:
----------------
// as __get does not return a reference
// the output should IMHO look like this:
object(A)#1 (1) {
["q"]=>
array(0) {
}
}
// if you guys think the output should be
// different, please do explain it!
Actual result:
--------------
object(A)#1 (1) {
["q"]=>
CRASH!
