obviosly the last is z**4. dtypes are the same for y and z (float64). I ran into this yesterday and fixed it. It should be OK in SVN now.
One addition:
In [5]: z = arange(10, dtype=float) In [6]: z **= 1 In [7]: z zsh: 18263 segmentation fault ipython This one is still there however. I'll look at it.
