Description:
------------
The script

<?php
datefmt_create('', IntlDateFormatter::NONE, IntlDateFormatter::NONE, "\xff", IntlDateFormatter::GREGORIAN, 'a');

Produces this output:

[Sun May 13 23:39:54 2012]  Script:  '/home/nikic/dev/Phuzzy/results/workingFile1_memleak.php'
/home/nikic/dev/php-src/ext/intl/intl_convert.c(78) :  Freeing 0xB69401E4 (4 bytes), script=/home/nikic/dev/Phuzzy/results/workingFile1_memleak.php
/home/nikic/dev/php-src/Zend/zend_alloc.c(2529) : Actual location (location was relayed)
=== Total 1 memory leaks detected ===

The reason is that if an error occurs in http://lxr.php.net/opengrok/xref/PHP_TRUNK/ext/intl/dateformat/dateformat.c#109, then svalue isn't freed.
