[Numpy-discussion] strange test failure in Cython code with numpy master

Hi, There's a test failure in scipy/io/matlab/mio_utils that shows up with numpy master but not 1.5.1, see http://projects.scipy.org/scipy/ticket/1512 I have a fix here: https://github.com/rgommers/scipy/commit/4ade7829649b9e2c251f5f7f370781b16fc..., but I don't really understand why the code is failing in the first place. This is the relevant part: - arr = np.squeeze(arr) - if not arr.shape and arr.dtype.isbuiltin: # 0d coverted to scalar - return arr.item() - return arr + arr2 = np.squeeze(arr) + if (not arr2.shape) and arr2.dtype.isbuiltin: # 0d coverted to scalar + return arr2.item() + return arr2 All it does is rename arr to arr2. It fails with both Cython 0.13 and 0.15. Any idea? Ralf
