Thanks. The whole html.c was rewritten for trunk, if you could give it
more emphasis it would be nice.

Description:
------------
Attached code crashes on PHP trunk debug build (64 bit). Looks like a
null pointer deref, so I assume it's not security related.
Test script:
---------------
<?php
/* Prototype : array get_html_translation_table ( [int $table [, int
$quote_style [, string charset_hint]]] )
*/
$tt = get_html_translation_table(acos(1.01), $quote_style, "UTF-8");
?>
Expected result:
----------------
==23063== Invalid read of size 8
==23063== at 0x6AFEEE: zif_get_html_translation_table (html.c:1625)
