Hey Stefan, It seems to come from the call to __Pyx_GetBuffer, which is PyObject_GetBuffer in python 3. Maybe this is Python 3 not checking for an extent of 1, but instead only checking the stride (which is a multiple of the itemsize)? Maybe Nathaniel or Sebastien can shed more light on this matter.
