This is a complicated issue to describe but i think the bottom line is that the test is just wonky here. the behaviour it's checking for is: wrong in old numpy, but we do it anyway (bug) wrong in current numpy without RELAXED_STRIDES, and we get it right (I.e. don't do it, fixed bug) correct in current numpy with RELAXED_STRIDES (and I think the test will pass if you build 1.8 this way?) (fixed bug again, since the definition of "correct" flipped) correct in future numpys
(@seberg, does that look right?) I guess maybe we could go back and make sure it stays broken in 1.8, but it's probably not worth the trouble because this is such a corner case. Nothing real is going to break because of this AFAICT. -n On 2 Oct 2013 08:31, "Christoph Gohlke" <[email protected]> wrote: > On 9/30/2013 8:17 AM, Charles R Harris wrote: > >> Hi All, >> >> NumPy 1.8.0rc1 is up now on sourceforge >> <http://sourceforge.net/**projects/numpy/files/NumPy/1.**8.0rc1/<http://sourceforge.net/projects/numpy/files/NumPy/1.8.0rc1/>> >> .The >> binary builds are included except for Python 3.3 on windows, which will >> arrive later.
