Description:
------------
The following simple code causes php process to crash (SIGSEGV) - both in cli and fpm.

Actually tested on PHP 7.1.17 an PHP 5.6.33. I am unable to get newer one.

Test script:
---------------
$config = array(
	'word-2000'=>true,
);
$tidy = new Tidy();
$tidy->parseString('<html xmlns:o=""><div class="">', $config);
$tidy->cleanRepair();

I can confirm the segfault with current PHP master using libtidy
5.2.0-2 (Debian Stretch) aka. 2016/04/07.  If the class attribute
is not empty, no segfault occurs for me, so this might be caused
by tidy-html5 issue 591[1], which is resolved as of libtidy 5.6.0.

I have verified that libtidy 5.4.0 causes a segfault, but 5.6.0
does not, so this is a resolved upstream issue.
