Bug Type: *XML functions
Description: XML functions no longer work in objects
Yes. If these lines are used in an object's constructor:
$this->parser = xml_parser_create();
xml_set_object($this->parser, $this);
xml_parser_set_option($this->parser, XML_OPTION_CASE_FOLDING, true);
xml_set_element_handler($this->parser, 'startElement', 'endElement');
xml_set_character_data_handler($this->parser, 'defaultHandler');
... Apache will segfault with the following backtrace:

I believe it's still a problem, but I'll have to recreate my test case. I'll try and
get to it soon.

With today's CVS, including Andrei's latest change to xml.c (rev. 1.61), I can
generate a backtrace for the segfault that occurs when calling the xml_* routines from
the constructor:
Starting program: /usr/local/src/apache_1.3.12/src/httpd -X
Program received signal SIGSEGV, Segmentation fault.

If you're referring to Andrei's changes that accept the array($this, 'fooHandler')
syntax, no, it doesn't fix my problem, and I actually haven't gotten the new syntax to
work correctly, either. I'll try and look into it some more later today.
