Description:
------------
Configure Command => cscript /nologo configure.js  "--enable-snapshot-build" "--with-gd=shared"
Using php.ini-recommended
-----
I am trying to parse about 4,000 xml files (each about 100-900KB in size). The script I am using simplexml_load_file(). I get an out of memory error after about 800 files.

I found bug #38604 and ran the script from that report (I copied it below) and quickly got the out of memory error.
Bug #38604 says "This bug has been fixed in CVS."  Was this really fixed or was the bug report just closed? If it was really fixed, is the fix in 5.2.0?

Reproduce code:
---------------
<?php
  $xml = '<root><node></node></root>';
  $xmldata = simplexml_load_string($xml);
  while (true) {
    $foo = $xmldata->node;
    foreach ($foo as $node)
    {
    }
  }
?>




Actual result:
--------------
G:\x>php test_bug38604.php
PHP Fatal error:  Out of memory (allocated 839122944) (tried to allocate 2013265
92 bytes) in G:\x\test_bug38604.php on line 8
