New Comment:
In Moodle (http:/moodle.org), this issue causes troubles in several
areas, including SSO support via MNet. Today, I was debugging some SSO
problem in Moodle/Mahara and tracked it down to this xml_parse() issue.
I have published a patch with workaround for the SSO in Moodle at
http://moodle.org/mod/forum/discuss.php?d=101459#p753158
In this particular case, the combination was PHP 5.2.13-pl0-gentoo and
libxml 2.7.3 (note that this combo is supposed to be fixed already).

HTML is not XML so non issue as the sax parser is not meant to handle
HTML
If PHP is not linked against 2.7.3 or higher it wont work either.
So back to "Compile PHP (5.2.9 or higher) against the newer libxml
(2.7.3 or
higher)" as most of those search results even tell you. Without phpinfo
and your
sample code I would say the problem is on your end

Regarding your e-mail message, please let's continue this discussion
publicly. It's established that this bug can happen with any (HTML)
input, so there's no point exposing my own. Check out
http://www.google.com/search?q=libxml+%2Bbrackets for tons of example
code.
But most importantly, is it possible that all this time no one ever
posted a bug about it in libxml's own tracker? If so, I think I'll post
something there soon.

Again, I use libxml v2.7.7 (with PHP v5.2.14).

To hopefully close this once and for all:
Compile PHP (5.2.9 or higher) against the newer libxml (2.7.3 or
higher).
PHP code change:
http://svn.php.net/viewvc/php/php-src/branches/PHP_5_2/ext/xml/compat.c?
r1=272374&r2=273286
Libxml code change:
http://svn.gnome.org/viewvc/libxml2/trunk/parser.c?r1=3803&r2=3807

It still happens to me even in libxml v2.7.7.
Please take it seriously. At least mention in what scenarios does it
happen and does it have a link in libxml's own bug tracker.
