Description:
------------
After I use the XSLT extension to process a huge file, I got an error
on the Apache error_log and a blank page on the browser. The error is:

*** glibc detected *** double free or corruption (fasttop): 0x08236cc8
***
[Wed Feb 01 08:56:12 2006] [notice] child pid 7121 exit signal Aborted
(6)

Reproduce code:
---------------
http://pastebin.com/533629

Expected result:
----------------
A regular HTML page and no error on error_log.

Actual result:
--------------
Sometimes it becomes blank and after some realoading it works, but
*always* with an error message on error_log.

I tested the code on all the ways I could but the only solution was
downgrade PHP to 4.4.2 with Sablotron support.

Then everything run fine (same Apache version, same OS), the only
negavite thing is that it takes a lot of time to show the results on
the browser, while using PHP 5.1.2 it was very fast.
