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.

Wasn't this just fixed in cvs??

All of my attempts to reduce the problem to a short script have failed, but I have
examples of working and non-working code you can look at.
I've made them available here: http://orca.gaiaservers.com/work/xml.tar.gz
xml.php works fine.
help.xml is the XML source file used in the following two files.
Help1.php calls the xml_* functions from the constructor and doesn't work.
Help2.php calls the xml_* functions from a separate init method and does work.

[2000-08-21 09:07:46] [EMAIL PROTECTED]
could you please provide an example of a runnable short script and XML file that
doesn't work?
