[Zope3-dev] expat failure in Zope3

[Jeremy Hylton]

I just tried to run the Zope3 test suite.  I get a segfault in
testDirectives that appears to be related to expat.  I've using Python
2.2 CVS and expat 1.95.5.

The specific test is:
testAdapter (Zope.App.ComponentArchitecture.tests.testDirectives.Test)

The GDB stack trace up to the first call from Python to expat is:
