    Hi All,
       We have just bought ourselves an AMD64 machine (HP DL145) and I have
    put 5.3-BETA5 on it. This is our first foray into 5.x, so far we have
    kept all our servers on 4.x. The server is meant to be a Zope server,
    but I am having trouble with python.

    Python 2.3.4 as built from ports cannot pass its own unit tests on this
    platform, specifically it fails test_re.py in about the 4th test
    (something to do with catching infinite recursion on a regular
    expression). The test just core dumps (as does trying to start Zope).
    I thought this was the well known 'FreeBSD has a tiny pthread stack
    size' issue. This is fixed in recent pythons (and the ports) by calling
    pthread_setstacksize to increase the stack to 1MB.

    I've tried this on 5.3-BETA5/AMD64, but to no avail. If I compile
    python *without* thread support, then the unit test passes. So I think
    it is related to threads. I've not managed to keep my finger on the
    -current development pulse, but wasn't threads re-written in 5.x? Or
    was it just the scheduler (I am using whichever scheduler 5.3-BETA5 uses
    by default).

    I've even tried raising the stack size to 64MB in python, but still it
    core dumps.

    Anyone else using python on 5.x? Can you test it passes its regex unit
    tests? As currently I'm unsure if the problem is related to:

    1) AMD64 support
    2) 5.x's new threads and/or scheduler
    3) something else :)

    I'm pretty sure I've heard of people running Zope on 5.1 (I'm guessing
    it was i386) so I'm thinking it is a 64-bit issue.

    -Matt
