Comment (by FabriciO):
Sorry, as I got numpy from bleeding-edge apt-get repository (cf http
://deb-scipy.alioth.debian.org/), I was thinking that I have a version
with the bug fixed.
But with the previous example, I have the following result:
{{{
>>> import numpy
>>> numpy.__version__
'1.0rc1'
>>> numpy.lib.polynomial.roots(numpy.lib.polynomial.poly1d([1,0,0]))
array([], dtype=float64)
}}}
I'll wait debian-scipy-team release...
Sorry for having reopened the ticket.
