Description:
------------
Hi, when I set $preferences['line-length'] = -1, 
iconv_mime_encode will get segmentation fault on linux.

Reproduce code:
---------------
<?php
$preferences = array(
        "scheme" => "B",
        "input-charset" => "ISO8859-1",
        "output-charset" => "UTF-8",
        "line-length" => 76,
        "line-break-chars" => "\n"
);

$preferences["line-length"] = -1;
var_dump(iconv_mime_encode("Subject", "This is encode test ", $preferences));
?>


Expected result:
----------------
Just a warning of line-length can't be less than 0

Actual result:
--------------
Segmentation fault

Please try using this CVS snapshot:

  http://snaps.php.net/php5.1-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5.1-win32-latest.zip

Works fine here (tm):
string(49) "Subject: =?UTF-8?B?VGhpcyBpcyBlbmNvZGUgdBCyjQg=?="

Hi, I have tried php5.1-latest.tar.gz on linux, but it also got segmentation fault. You may need to check it on linux.
