I have confirmed it,
It seems like this is a garbage collection issue and very likely a ref count one.

How can these kind of things can be fixed?

    I also think the same. There is some problem with my python

    Because a similar installation python-2.6.4 and numpy-1.3.0 which
    I did elsewhere does not seg fault for the same code.

    But I need your help to figure it out.
    Can you please elaborate on ref count bug? that might help.

        I mean building numpy 1.3.0 against python 2.6.1 instead of
        2.6.4 -
        since the crash happen on a python you built by yourself,
        that's the
        first thing I would look into before looking into numpy or
        python bug.

        Very unlikely, this looks like a ref count bug,

        cheers,

Hi,
Based on the list, I always suspect lapack/atlas issues when I see problems related to eigenvalues.

What is configuration including lapack/atlas ie the output from 'numpy.show_config()'?
