DOMXML still has problem with SIGSEGV. Now, after shutdown, php_free_xml_dom got NULL
pointer and xmlFreeDoc double free or what. I hope, that problem is in mine, but joey
please look at this.
My script:
--- test.php ---
<?php
$doc = xmldocfile('./test.xml');
?>
--- text.xml ---
<?xml version="1.0" encoding="iso-8859-2"?><root>
<nothing/>
</root>
And result is:
Program received signal SIGSEGV, Segmentation fault.

I try to debug and:
=php_domxml.c(v1.74):2269 in xmldocfile()
..
docp = xmlParseFile(Z_STRVAL_P(arg));
...
=print *docp
{_private = 0x0, type = XML_DOCUMENT_NODE, name = 0x0,
children = 0x82b0658, last = 0x82b0658, parent = 0x0, next
= 0x0,
prev = 0x0, doc = 0x82b05c0, compression = -1, standalone = -1,
intSubset = 0x0, extSubset = 0x0, oldNs = 0x0, version = 0x82b0618 "1.0",
encoding = 0x82b06e8 "iso-8859-2", ids = 0x0, refs = 0x0,
URL = 0x82b0628 "./test.xml", charset = 1}.
=
look's like file was parsed without problem, *return_value look's good. But
zend_list_addref(ret) return ret, not return_value. Is it right?
