#2029: Should not allow views of NA-masked arrays which change the array size
------------------------+---------------------------------------------------
 Reporter:  mwiebe      |       Owner:  somebody
     Type:  defect      |      Status:  new     
 Priority:  high        |   Milestone:  1.7.0   
Component:  numpy.core  |     Version:  devel   
 Keywords:              |

 Chuck posted an example:

 {{{
 Looks like views of masked arrays have other problems:

 In [13]: a = ones(3, int16, maskna=1)

 In [14]: a.view(int8)
 Out[14]: array([1, 0, 1, NA, 1, NA], dtype=int8)
 }}}

 This looks like a serious bug to me, to avoid memory corruption issues it
 should raise an exception.
