[Numpy-discussion] nasty bug in 1.8.0??

[Frédéric Bastien]

Just don't compile with NPY_RELAXED_STRIDES_CHECKING to have the old
behavior I think (which is an not always the same strides depending of
how it was created, I don't know if they changed that or not).

Do someone else recall the detail of this?

Fred

p.s. I didn't do this or asked for it. But this help test your
software to don't depend of the strides when shapes is 1.
