#652: linalg.eig takes 100% cpu and never ends
-------------------------------+--------------------------------------------
 Reporter:  PeterC             |       Owner:  cdavid
     Type:  defect             |      Status:  new   
 Priority:  normal             |   Milestone:  1.0.5 
Component:  Official binaries  |     Version:  none  
 Severity:  normal             |    Keywords:        
-------------------------------+--------------------------------------------
 Using the official binaries for 1.0.4-py2.4 the following code never ends

 {{{
 from numpy import arange, float64
 from numpy.linalg import eig
 a = arange(13*13, dtype = float64)
 a.shape = (13,13)
 a = a%17
 eig(a)
 }}}

 however this completes on the official 1.0.3.1-py2.4

 This may be related to #627 but I do not have python 2.5 so I cannot try
 the binaries posted.

 My system is
 Windows XP, Intel Xeon 5140
