Bug in inherited static class variables

[Vladan Zajda]

Hello,
There is a bug in inherited static class variable when using cached php. The value of inherited static variable is altered back to its initial value.
Tested only on WinXP/PHP 5.1.6 using XCache 1.0.2 but this seems to be global bug.

Here's an example:

<?php
         
class B {
   static protected $B = 'initial value';
  
   public static function setB($value) {
      if ($value) {
         self::$B = 'different value';
      }
   }

   public function showBinB() {
      echo "static \$B in B = " . self::$B . "<br />";
   }
}

class C extends B {
   public function showBinC() {
      echo "static \$B in C = " . self::$B . "<br />";
   }    
}

B::setB(true);
$c = new C();
$c->showBinB();
$c->showBinC();

?>

in [199], i should have checked it with --enable-xcache-test :)

[moo]

static variable is not handled correctly, which breaks testcase Zend/tests/bug28442.phpt
