[PHP-BUG] Bug #51967 [NEW]: iconv_mime_encode() eats all memory

From:             
Operating system: linux
PHP version:      5.2.13
Package:          *Mail Related
Bug Type:         Bug
Bug description:iconv_mime_encode() eats all memory

Description:
------------
We got this error:



PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
allocate 2194780439 bytes) in



After examining the reason, I found this test to reproduce it.



Because we don't have 5.2.13 in production, this is only tested with
5.2.12, but as far as I know, there was no change here, since that, so it
should also be reproduce able with 5.2.13.





Test script:
---------------
<?php





$string = 'Короткое замыкание в цепи датчика
емкостного водонагревателя';



error_log(phpversion());

error_log ("1");

error_log (iconv_mime_encode( 'Subject', $string, array(

    'scheme' => 'Q',

    'input-charset' => 'utf-8',

    'output-charset' => 'utf-8',

    'line-length'    => 74,

    'linke-break-chars' => "\r\n")

));



error_log("2");

Actual result:
--------------
The script prints out only "1" and breaks down with the fatal error. Take
care! It eats all memory if no limits are here!
