Hi Martin
Given that its failing on a call to libc I would do a quick run with strace and ltrace.
That was my segfault, not Martin's. I suspect hardware, as it's very non-deterministic (a small pure-Python script that runs every 5 minutes segfaults once in a few months).
(In your case ltrace will be probably be more useful.) You will be able to see the calls into the libraries and you should see immediately if your segfault is inside expat or not. (ltrace output will be very long ;-)

I'm not sure if this is a Python issue or a zope issue. We're getting a segfault on 64-bit SuSE Linux (SLES 11), originating from z3c.autoinclude, which in turn called zope.configuration's<include /> implementation. This calls expat, which then crashes (no error, log message, or core file, but it has all the markings of a segfault) during parsing of the file.
On recent Ubuntu versions segfaults get recorded in dmesg and end up in /var/log/kern.log like this:
Mar 22 02:10:03 fridge kernel: [7804719.781375] python[10447]: segfault at 7fff84a7c000 ip 00007fff83aae7cb sp 00007fff84a7bd98 error 7 in libc-2.9.so[7fff83a2b000+168000]
I assume that's a standard kernel feature now (we've 2.6.28, x86_64).
