Description:
------------
Since php 5.0.1, extract($GLOBALS, EXTR_REFS) seems to corrupt code memory and cause various random problems.  In my test case, it caused COM("someobject") to always return null, and in another case it just caused some strange output of a "1" instead of the expected strings.  I never had a problem in php 5.0.0 up to CVS snapshot php5.0-win32-200407301630.  Commenting out extract($GLOBALS, EXTR_REFS) fixes all strange behavior.

I had a similar problem in php 4 which I reported as bug id 25708.  That bug was fixed and I never had a problem again until 5.0.1.

Reproduce code:
---------------
  extract($GLOBALS, EXTR_REFS);
  $query = new COM("IXSSO.Query");

  if(is_object($query) == false) {
    var_dump($query);
    print "Can't create IXSSO Query object.";
    exit();
  }


Expected result:
----------------
Nothing

Actual result:
--------------
PHP has encountered an Access Violation at 01D5F185
