Description:
------------
OpenBSD 3.4 with the stock apache.  PHP 4.3.3 from the openbsd ports tree.  (./configure --with-apxs=/usr/sbin/apxs --without-mysql --enable-xml --enable-wddx --enable-cli --with-iconv=/usr/local --with-gettext=/usr/local --enable-dio --with-pear=/var/www/pear --enable-bcmath --enable-session --enable-trans-sid --enable-calendar --enable-ctype --enable-ftp --with-pcre-regex --with-posix --enable-sockets --enable-sysvsem --enable-sysvshm --enable-yp --with-recode=/usr/local --enable-shared --disable-static --disable-rpath --with-config-file-path=/var/www/conf --enable-inline-optimization --with-pic --with-openssl --with-zlib --prefix=/usr/local --sysconfdir=/etc)

xslt and other extensions are loaded as shared objects:
extension=xslt.so
extension=domxml.so
extension=gd.so
extension=mcrypt.so
extension=mhash.so
extension=pgsql.so
extension=mysql.so

Using xslt_process from a php script causes apache to seg fault.

Reproduce code:
---------------
$this->xh = xslt_create();
$this->arguments = array();
xslt_set_encoding($this->xh, "ISO-8859-2");
-snip-
$result = @xslt_process($this->xh, $this->xml, $this->xsl, NULL, array(), $this->arguments);

The call to xslt_process causes the seg fault.  $this->xml and $this->xsl are set to .xml and .xsl filenames.

Expected result:
----------------
I was hoping it would do what xslt_process is supposed to do, instead of crashing apache  :)

Actual result:
--------------

1. What other info should I have given?  I did what the bug report said, and included configure lines and a backtrace.

2. Whatever you say, I am sure that has alot to do with bug reports right?

3. Thanks, this was all that's needed.
