Even at the "enterprise" (and I use that in the worst sense of the word) level, 2.6 is not acceptable...

You really should be on 2.7 at the absolute minimum. Come on, these rest of us are on 2.8 or 2.9 now ;-)

The profiler is here (zope 2.6.1):
/Control_Panel/DebugInfo/manage_profile

I know 2.6 is old, but in an enterprise environment upgrades happen slowly :)

Also, what's the Zope profiler you're mentioning? Dieter Maurer's ZopeProfiler?

I doubt it will be investigated if it only happens with ancient Zope and python versions.

If you could reproduce (and explain how to reproduce!) using Zope 2.8 or 2.9 with python 2.4.2, then that would be a different matter.

Is this bug ever going to be investigated?

Several of our internal products reference it:
from xml.dom.minidom import Node
from xml.dom import minidom

However, I can cause the crash with no product instances installed, but the product itself installed.
The problem here is between the pyexpat shared lib and the zope profiler, probably any zope product that uses PyXML will have this same crash.

Okay, now can you tell us what's using PyXML?

The debugging and profiling page in the control panel:
/Control_Panel/DebugInfo/manage_workspace

What is the "zope debugger" you speak of?

What do you have installed that is using PyXML?

Whoops forgot the PyXML version, we're just using the python2.1-xml debian package from debian stable, looks like version 0.7.
http://packages.debian.org/stable/interpreters/python2.1-xml

When using the PyXML module with the zope debugger installed, hitting any page will cause zope to segfault, attaching GDB to the python process the last thing on the stack before the crash was:
 0x402a6587 in XML_ExpatVersionInfo ()
from /usr/lib/python2.1/site-packages/_xmlplus/parsers/pyexpat.so
