Hi Travis, I just had a quick look at Numeric3, checked out with cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/numpy co -D 2005-03-18 -P Numeric3 (as you already warned, the current CVS does not compile for me). After that I saw Michiels mail, so my results below just adds another "data-point"... On Fri, 18 Mar 2005, Michiel Jan Laurens de Hoon wrote:

I wanted to let people who may be waiting, that now is a good time to help with numeric3. The CVS version builds (although I"m sure there are still bugs), but more eyes could help me track them down.
Currently, all that remains for the arrayobject is to implement the newly defined methods (really it"s just a re-organization and re-inspection of the code in multiarraymodule.c to call it using methods).

When using ndarray, I got a core dump using "zeros":

Have you already found the origin of this? If so, which version should I download for further testing? If not, if you need help in debugging this one, just let me know (+some hints how to tackle this). Best, Arnd
