I think, this is a bug. But not the header() functions, it is a bug of
readfile() function.I tested it over and over, no error is reported,
not even the die() stops it, after that I've changed the readfile()
with ` echo file_get_contents() ` and works just perfectly. I tried to
compare the to results and they don't match, readfile() doesn't get all
the data and get's it wrong too.

Description:
------------
Under php-4.3.10 this method works just fine. But with php-4.4.1 and
php-4.4.2 the application crashes(mostly MS Word, because I try to open
rtf documents and this is the default application).
The script uses header function to get the document from server.

Reproduce code:
---------------
to get the file:
<a href="fileopen.php?folder=subfolder&filename=file.rtf">file.rtf</a>

fileopen.php:
<?
        if(!isset($_GET["folder"])) $_GET["folder"]=NULL;
        if(!isset($_GET["subfolder"])) $_GET["subfolder"]=NULL;
        if(!isset($_GET["id"])) $_GET["id"]=NULL;
        if(!isset($_GET["filename"])) $_GET["filename"]=NULL;
        if($_GET["folder"]=="somatie")
        {
                $name="../".$_GET["folder"]."/".$_GET["filename"];
        }
        else
        {
                if($_GET["subfolder"]!=NULL)
                        
$name="../".$_GET["folder"]."/".$_GET["subfolder"]."/".$_GET["id"].str_replace("*","&",$_GET["filename"]);
                else
                        
$name="../".$_GET["folder"]."/".$_GET["id"].str_replace("*","&",$_GET["filename"]);
        }
        $file_extension=strtolower(substr(strrchr($_GET["filename"],"."),1));
        switch($file_extension)
        {
        case "pdf": $ctype="application/pdf"; break;
        case "exe": $ctype="application/octet-stream"; break;
        case "zip": $ctype="application/zip"; break;
        case "doc": $ctype="application/msword"; break;
        case "csv":
        case "xls": $ctype="application/vnd.ms-excel"; break;
        case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
        case "gif": $ctype="image/gif"; break;
        case "png": $ctype="image/png"; break;
        case "jpeg":
        case "jpg": $ctype="image/jpg"; break;
        case "mp3": $ctype="audio/mpeg"; break;
        case "wav": $ctype="audio/x-wav"; break;
        case "mpeg":
        case "mpg":
        case "mpe": $ctype="video/mpeg"; break;
        case "mov": $ctype="video/quicktime"; break;
        case "avi": $ctype="video/x-msvideo"; break;

        //The following are for extensions that shouldn't be downloaded
(sensitive stuff, like php files)
        case "php":
        case "htm":
        case "html":
        case "txt": die("<b>Cannot be used for ". $file_extension ."
files!</b>"); break;

        default: $ctype="application/force-download";
        }
// send the right headers
        header("Pragma: no-cache");
        header("Expires: 0");
        header("Cache-Control: no-store, no-cache, must-revalidate,
post-check=0, pre-check=0");
        header("Content-Description: File Transfer");
        header("Content-Type: $ctype");
        header('Content-Disposition: attachment;
filename="'.$_GET["filename"].'";');
        header("Content-Transfer-Encoding: binary");
        header("Content-Length: ".filesize($name));
// dump the picture and stop the script
        @readfile($name);
        exit;
?>


Expected result:
----------------
The file should be opened with the default application.

Actual result:
--------------
Default application crashes.
