#1483: scipy.interpolate.interp1d thows "ILLEGAL INSTRUCTION"
 Reporter:  hamogu             |       Owner:  somebody   
     Type:  defect             |      Status:  new        
 Priority:  normal             |   Milestone:  Unscheduled
Component:  scipy.interpolate  |     Version:  0.9.0      
 Keywords:  interp1d kind      |  
 scipy.interpolate.interp1d crashes python, with kind = 'quatratic',
 'cubic', 3,...
 Basically everything I tried except kind = 'linear' crashed scipy.

 >>> import numpy as np
 >>> import scipy.interpolate
 >>> f =  scipy.interpolate.interp1d(np.arange(100), np.arange(100),kind =
 Illegal instruction

 As per instruction on http://www.scipy.org/BugReport I also add output
 from gdb here:

 This GDB was configured as "x86_64-redhat-linux-gnu".
