 Operating System: Mandriva Linux

What is the current status of a fix (in contrast to a work around)?
This issue breaks lots of web apps (Wordpress as we heard here, Typo3 as
we heard in our bug tracker at Gentoo) and considering that the last
release of 5.2.x is supposed to be released tomorrow, this sounds rather
urgent...

Downstream bug for Gentoo:

case of such library interaction issues)

To build with expat just read my earlier posts on this bug where I've
shown how we did this in our recent Mandriva 2009 release.

I already have libxml 2.7.2

Can anyone help me how to "build PHP with libxml2 <= 2.6.32 or 
build ext/xml with expat."? Any link on how to so it?

Thanks.

just use the example in the manual. Your change simply gets predefined

entities working but breaks all other cases. I'm currently looking at 
getting the change in libxml2 that caused this reverted. The problem 
stems from the magic needed to emulate expat behavior as its not native

in libxml so non-standard use of the libxml sax hooks was needed.

Rob, do you have a test case for the regression caused by my test
patch, so I can look at that further?
