Bug description:  strtr() crashes when $from argument is empty string or null, 
with Unicode ON

Description:
------------
strtr() crashes on php6 with unicode ON , when $from argument is given as
any of the following:
empty string
Null

e.g:
var_dump( strtr("hello", array("" => "string") ) );
var_dump( strtr("hello", "", "string") );

This is applicable for PHP6 with Unicode.

Reproduce code:
---------------
<?php
var_dump( strtr("hello", array("" => "string") ) );
var_dump( strtr("hello", array('' => "string") ) );
var_dump( strtr("hello", array(null => "string") ) );
var_dump( strtr("hello", array(NULL => "string") ) );

var_dump( strtr("hello", "", "string") );
var_dump( strtr("hello", '', "string") );
var_dump( strtr("hello", NULL, "string") );
var_dump( strtr("hello", null, "string") );
?>

Expected result:
----------------
unicode(5) "hello"
unicode(5) "hello"
unicode(5) "hello"
unicode(5) "hello"
unicode(5) "hello"
unicode(5) "hello"
unicode(5) "hello"
unicode(5) "hello"

Actual result:
--------------
On Windows: crashes
On linux(RHEL4):
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
allocate 1066789985 bytes) in %s on line %d
