Description:
------------
Hello together,

like last time in bug #29599, another apache module is using
libxml2 and registering a global create/delete node callback.

Right now PHP crashes on our site while using the dom extension
because the callback still points to the other module. Guess libxml2
is to blame for providing -global- callbacks.

Attached patch makes sure everything is clean and shiny
when enter/leaving the request handled by PHP. The performance
impact should be close to nothing. Hope it's useful to someone else.

The link somehow gets cropped by the bugtracker,
the filename is php-5.2.6-fix-libxmlpp-clash.patch

Please provide patches against HEAD, PHP_5_3 and PHP_5_2 branches.

You should report this to the author of the other module. They should 
fix their code and not be abusing the libxml2 globals like this.
