Bug description: session - objects in arrays

I'm using php.ini-optimized with register_globals = Off, so I access session variables using $HTTP_SESSION_VARS["blah"]. This is defined as an array of objects. I'm able to access properties such as $HTTP_SESSION_VARS["blah"][0]->property, but I can't run methods by doing $HTTP_SESSION_VARS["blah"][0]->method(). The following test script illustrates the problem, reloading the page should increase the array size of "blah" each time. I found that I could work around the problem by copying the session variable to a local variable, doing the methods on that, and then copying back. I compiled PHP as a dynamic DSO module using:

./configure --with-mysql --with-apxs=/usr/local/apache/bin/apxs

Here is the test script:

/* reload the page to increase the array size of "blah" */
class Test {
   var $item;
   function run() {
      $this->item = 1234;
   }
}

session_start();
session_register("blah");
if (!isset($HTTP_SESSION_VARS["blah"])) {
   $HTTP_SESSION_VARS["blah"] = array();
}

echo "array size before = ",sizeof($HTTP_SESSION_VARS["blah"]),"<br>n";
$S = sizeof($HTTP_SESSION_VARS["blah"]);
$HTTP_SESSION_VARS["blah"][$S] = new Test;

/** this doesn't work *******************/
// $HTTP_SESSION_VARS["blah"][$S]->run();
/****************************************/

/** this works **************************/
$SESSION = $HTTP_SESSION_VARS;
$SESSION["blah"][$S]->run();
$HTTP_SESISON_VARS = $SESSION;
/****************************************/

echo "array size after = ",sizeof($HTTP_SESSION_VARS["blah"]),"<br>n";
