Description:
------------
phpinfo(); http://corgfx.com/info.php

preg_match_all is missing valid results while running in a loop of documents. There are 12 valid matches per document, but starting from document 5 only 11 results are returned. When the script is run "only" on document 5 or 6 or 7 etc, all 12 results are returned properly.

The script returns no warnings or errors when running in the loop and missing the 12th result.

Test script:
---------------
This is an example of the code being used:

    for ($i = 0; $i <= $pages; $i++) {
        shell_exec(" /usr/local/bin/curl -o /tmp/coffee_process_ajax.tmp -b PHPSESSID=$cookie -d \"category_id=$cat&page_index=$i\" http://www..........com/html/results_ajax.php");
        $filename = "/tmp/coffee_process_ajax.tmp";
        $handle = fopen($filename, "r");
        $adata = fread($handle, filesize($filename));
        fclose($handle);
        preg_match_all("/<table class=AssetContent>(.*?)<\/table>/", str_replace("\n","",$adata), $ajarray);
        $saveThis[]=$ajarray[0];
    }

Expected result:
----------------
The expected result is all 12 results to be returned with and without the loop.

Actual result:
--------------
Returns only 11 results starting at $page=4 (the 5th document) while running in the loop. Returns all 12 results for $page=4 when not running in the loop.
