Operating system: Linux
PHP version: 4.3.4
PHP Bug Type: Reproducible crash
Bug description: domxslt->process causes segfault
Description:
------------
PHP segfaults when domxslt->process() is called.
It seems to me, that this error is caused by memory corruption, cause I
can see, using printf(), in node_wrapper_free(), that wrapper contains
some html-code sometimes.
Reproduce code:
---------------
//full code could be grabbed from:
//http://tony2001.phpclub.net/temp/domxslt.tar.gz
$xml = domxml_open_mem(file_get_contents("./area_name.xml"));
$xslt = domxml_xslt_stylesheet_file('./area_list.xsl');
$xslt->process($xml, Array());
Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
