Component:  scipy.sparse.linalg  |     Version:  0.9.0 
 Keywords:  arpack, segfault     |  

Comment(by pv):

 Then the fix probably should be merged in. It's pretty straightforward and
 should be correct.

 The failures all have to do with single-precision. If it turns out we
 cannot resolve this (e.g. if the single precision Veclib turns out to be
 busted, or no solution comes up within a few weeks), we can just disable
 ARPACK single precision on OSX and mark the tests as known failures. My
 guess would be that not so many people need single-precision iterative
 solvers, so not having them would not be a blocker.
