Im running the code as a CLI application, i don't know if the bug
persist with the PHP module or CGI.

This is a little script that show the problem:

<?php

 function recurse_search($dir,$pattern)
          {     
          stdout_write("Recurse_search $dir,$pattern");
          $temp = "";
          $len = strlen($pattern);
          $d = @opendir($dir);
          if (!$d) die("Directory $dir not mounted or unavailable");
          clearstatcache();
          while($file = readdir($d))
                {
                
                if ($temp != "") break;
                
                if ($file[0]==".") continue;
                if ($file[0]=="#") continue;
                
                stdout_write($file);
                if (is_dir($dir.$file."/"))
                                {
                                stdout_write("DIR : $file");
                                $bof = 
recurse_search($dir.$file."/",$pattern);
                                }
                                else
                                    if (substr($file,0,$len)==$pattern)

                                                        {
                                                                close($d);
                                                                die($dir.$file);
                                                                return $dir.$file;
                                                        }

                  
                }
          closedir($d);
          return $temp;
          }
    }

  function stdout_write($content)
      {
      $fp = fopen("php://stdout","w");
      fwrite($content."\r\n");
      fclose($fp);
      }

print recurse_search("c:\\","system.ini");
?>
----------------------------------------------------
When i get back from a prior directory recursion, the
$file = readdir($d) stop working and the function exit.
