PHP Bug Type: Reproducible crash
Bug description: Segfault on combo of recursive array, class members and
variable variables
Description:
------------
When the code I've supplied is executed, PHP crashes, leaving a segfault
message in Apache's log.
The code looks a little perverse, though a variation on it had a real use
in my situation, but regardless, PHP shouldn't segfault, no matter how
perverse the code is :)
Reproduce code:
---------------
class MC {
public $Vars = array();
public function Execute() {
if (!defined('DONE')) {
define('DONE', true);
foreach ($this->Vars as $k => $v) { $$k = $v; }
$MyArr['Var'] = $MyArr;
$MC = new MC();
$MC->Vars = $MyArr;
$MC->Execute();
}
}
}
$MyArr = array();
$MyArr['Var'] = $MyArr;
$MC = new MC();
$MC->Vars = $MyArr;
$MC->Execute();
echo "Hello world.";
Expected result:
----------------
"Hello world." should be printed.
Actual result:
--------------
Nothing is printed, and a segfault line is added to
/var/log/apache2/error.log:
[Fri Nov 02 15:50:11 2007] [notice] child pid 23282 exit signal
Segmentation fault (11)
