If readonly protection is disabled a munmap(shm->ptr_ro, ...) is executed with ptr_ro = NULL.

Initializing shm->ptr_ro with XCACHE_MAP_FAILED is skipping the munmap().

Hi the following code produces wrong results and segfaults.

<?php

abstract class Foo {

protected function & a (){}

abstract function & b ();

}

class Bar extends Foo {

 protected function &a(){}

 public function &b()
 {
     $retval =& $this->a();
 }

}

$bar = new Bar();
$bar->b();
?>

• Expected result :

Notice: Only variable references should be returned by reference in /srv/www/htdocs/bug2.php on line 13 Notice: Only variable references should be returned by reference in /srv/www/htdocs/bug2.php on line 18

* Actual result :

at the first call : see expected result.

at the second call : Fatal error: Call to protected method Bar::a() from context 'Bar' in bug.php on line 17 and the apache child segfaults :(
