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 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38638&edit=1
