#1503: isolve and arpack test failures on OS X
---------------------------------+------------------------------------------
 Reporter:  rgommers             |       Owner:  wnbell
     Type:  defect               |      Status:  new   
 Priority:  normal               |   Milestone:  0.10.0
Component:  scipy.sparse.linalg  |     Version:  0.9.0 
 Keywords:                       |  
---------------------------------+------------------------------------------
 They are showing up after fixing #1472, but it's very well possible that
 they were there before (the test suite crashed, so this was never run on
 OS X after the addition of the shift-invert Arpack modes).
