     Type:  defect           |      Status:  new        
 Priority:  normal           |   Milestone:  1.0 Release
Component:  numpy.core       |     Version:  devel      
 Severity:  normal           |    Keywords:             
-----------------------------+----------------------------------------------
 <operator>.reduceat does not handle repeated indices correctly. When an
 index is repeated the neutral element of the operation should be returned.
 In the example below [0, 10], not [1, 10], is expected.

 {{{
 In [1]:import numpy

 In [2]:numpy.version.version
 Out[2]:'1.0b1'

 In [3]:a = numpy.arange (5)

 In [4]:numpy.add.reduceat (a, (1,1))
 Out[4]:array([ 1, 10])
 }}}
