No, just vanilla ./configure.

I rebuilt Python 2.2.3 / egenix-base-2.0.4 and had the same problem.

Because of this line from the backtrace:
#0  mxDateTime_FromDateAndTime (year=1, month=1, day=1, hour=1, minute=1, second=0) at mx/DateTime/mxDateTime/mxDateTime.c:333

mxDateTime.c:333 :

#ifdef MXDATETIME_FREELIST
    if (mxDateTime_FreeList) {
	datetime = mxDateTime_FreeList;
	mxDateTime_FreeList = *(mxDateTimeObject **)mxDateTime_FreeList;
	datetime->ob_type = &mxDateTime_Type;
->	_Py_NewReference(datetime);
    }
    else
#endif 
	 {
	datetime = PyObject_NEW(mxDateTimeObject,&mxDateTime_Type);
	if (datetime == NULL)
	    return NULL;
    }

I undefed MXDATETIME_FREELIST and rebuilt and everything seems fine.

This is not the root cause because, as mentioned, a rebuild of 
Python 2.2.3 / egenix-base-2.0.4 on this machine exhibited the same
problem.

My working production environment (different machine) is:
Python 2.2.3 (#1, Jun  5 2003, 13:06:29) 
[GCC 3.2.3 20030415 (Debian prerelease)] on linux2

and egenix-base-2.0.4

I rebuilt Python-2.2.3 / egenix-base-2.0.4 on production and it still
works.

So is it a gcc problem?
