[PHP-DEV] Bug #20175 (Static vars can't store ref to new instance)

[Moriyoshi Koizumi]

I've simplified the test code, and I still have got a strange result
with ZE2.

------------------------------------------------------
<?php
        function foo() {
                static $value;
                if (!isset($value)) {
                        $value = rand(0,100);
                }
                return $value;
        }

        function bar() {
                static $value;
                if (!isset($value)) {
                        $value = &rand(0,100);
                }
                return $value;
        }

        print zend_version()."\n";
        print foo()."\n";
        print foo()."\n";
        print bar()."\n";
        print bar()."\n";
?>
------------------------------------------------------

with ZE1
------------------------------------------------------
1.3.0

95
------------------------------------------------------

with ZE2
------------------------------------------------------
2.0.0-alpha3

------------------------------------------------------

Is this a known behaviour?
