#1801: Failure: test_noncentral_f in random
--------------------------+-------------------------------------------------
 Reporter:  rgommers      |       Owner:  somebody
     Type:  defect        |      Status:  new     
 Priority:  normal        |   Milestone:  1.6.0   
Component:  numpy.random  |     Version:  1.5.1   
 Keywords:                |  
--------------------------+-------------------------------------------------
 Reported by Christoph Gohlke against 1.6.0b2 on 64-bit Windows with MKL.
 Unlike #1768 this seems to be a real bug, not just about test precision.

 Christoph, could you please have a look at this? I haven't got a 64-bit
 Windows machine available.
