Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

$_ENV [ 'nFiles' ] = 0 ;
$_ENV [ 'nFolders' ] = 0 ;
$sPath = $prefixe . './' ; // define a file system

function _getmicrotime ( ) {
	list ( $usec, $sec ) = explode ( " " , microtime ( )) ;
	return ( ( (float) $usec + (float) $sec ) * 1000 ) ;
	};
	
function doSomething ( $sPath ) {
	$_ENV [ "nFolders" ]++ ;
	$a = glob ( $sPath . "*" ) ;
	if ( $a ) 
		while ( list (, $sFile ) = each ( $a )){
			if ( is_dir ( $sFile ) AND ! in_array ( $sFile , Array ( "." , ".." )))
				doSomething ( $sFile . "/" ) ;
			if ( is_file ( $sFile )){
				$s = file_get_contents ( $sFile ) ;
				$_ENV [ "nFiles" ]++ ;
				}
			}
	};
	
$nStart = _getmicrotime ( ) ;
if ( is_dir ( $sPath )) doSomething ( $sPath ) ; else die ( $sPath ) ;
echo 
	' - time: '. (int)( _getmicrotime ( ) - $nStart ) . 'ms ' .
	' - Files: '. $_ENV [ "nFiles" ] .
	' - Folders: '. $_ENV [ "nFolders" ] ;
