Comment(by pierregm):

 Confirmed, but it's a bit more complex than that:
 {{{
 >>>  a=np.array(zip((1,2,3),(1,2,3)),dtype=[('a',int),('b',float)])
 >>> a.dtype.names = ('a','c')
 >>> a
 array([(1, 1.0), (2, 2.0), (3, 3.0)],
       dtype=[('a', '<i8'), ('c', '<f8')])
 }}}
 So, it looks like the segfault shows up when renaming a field by the name
 of another existing field.
