Bug description: Looping of class member using foreach causes segfault
Description:
------------
This could be related to bug 31942.
When a global array variable is accessed in both the __construct & __get
method and subsequently looped using foreach, it causes segmentation fault
the second time the variable is accessed.
Reproduce code:
---------------
<?
$data = array(1, 2, 3);
class classA {
private $properties;
function __construct () { $this->properties = $GLOBALS["data"]; }
function __get ($prop) { return $GLOBALS["data"]; }
}
function loopValues () {
$a = new classA();
foreach ($a->values as $i => $v) { }
}
function dumpValues () {
$a = new classA();
var_dump($a->values);
}
loopValues();
dumpValues();
?>
Expected result:
----------------
array(3) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(3)
}
Actual result:
--------------
Segmentation fault
