[Pkg-exppsy-maintainers] Segfault example

[Per B. Sederberg]

Hi Yarik:

Did you have the chance to run the ridge regression example code that
is breaking on my machine?  Michael ran it on his machine and could
not reproduce the error.

This is getting quite weird and I'm not sure where to go from here.
It breaks at the same point (returning from the _train call) for all
of my actual data.  The call to the numpy.linalg.lstsqr runs with no
error and returns the correct values while inside the _train call, but
all goes haywire upon the return from that method when the python
garbage collection kicks in.

Any thoughts on how to proceed are more than welcome from all.

Thanks,
Per
