Bug description: Recode crashes/does not work on amd64
Description:
------------
When using recode extension on amd64 system I've got two states
- Crash (SIGSEGV)
- zero-length string output
from recode_string function.
This problem is relevant only on 64bit systems. Here is a little patch
which helps.

going to have

<?php
echo recode_string("utf-8..flat","aaaa");

Expected result:

should return aaaa
Actual result:

instead returns zero length string or crashes with sigsegv
