Hello,
I think there is a bug in mx.DateTime for egenix-mx-base-3.2.1, that
kills python when triggered:
help(mx.DateTime) kills python on Centos6 (RHEL 6 clone): *** buffer
overflow detected ***: python terminated
How to reproduce from a clean installation (tested on multiple computers):
wget http://downloads.egenix.com/python/egenix-mx-base-3.2.1.tar.gz
tar xvfz egenix-mx-base-3.2.1.tar.gz
cd egenix-mx-base-3.2.1
python setup.py install --home=/home/admin/
export PYTHONPATH=/home/admin/lib64/python
python
Python 2.6.6 (r266:84292, Jul 20 2011, 10:22:43)
