#497: The dot and inner products fail for large arrays on 64 bit linux using the
ATLAS libraries.

     Type:  defect   |      Status:  new            
 Priority:  high     |   Milestone:                 
Component:  Other    |     Version:  none           
 Severity:  blocker  |    Keywords:  dot inner crash
---------------------+------------------------------------------------------
 The problem is easy to exhibit:

 {{{
 In [2]: dot(eye(1000),eye(1000))
 Illegal instruction

 }}}

 The products work for smaller arrays, so I suspect either the output array
 or a work array is being created with the wrong size, probably a 64bit
 integer thing in the cblas interface. The example works on 32 bit linux.

 This ticket replaces #432
