The following does not raise an error:
a = np.arange(5)
a[a0] = a
although a.shape == (5,) while a[a0].shape == (4,)
I get in on python2.6.5, numpy 1.4.1 on win32, and python 2.6.5, numpy
2.0.0.dev8469 on linux64.

This has nothing to do with reusing ``a``::
b = np.arange(50)
a[a0] = b
a
array([0, 0, 1, 2, 3])
Note however that reusing ``a`` is unsafe.
(You will get all zeros.)

Hi all,
I am trying to install manually the latest releases of scipy and numpy on Mac
OSX 10.6 Snow Leopard. I previously used the dmg installer that is available,
but the numpy version is too new for some other modules I have and need on my
machine, so I went for a manual install of numpy 1.4

I was not aware that
a[b] = c
where b is an integer or boolean indexing array, is legal even if
a[b].shape != c.shape.
