#1895: segfault in numpy.subtract on MacOS X 10.5

 Reporter:  rowen              |       Owner:  rgommers   
     Type:  defect             |      Status:  new        
 Priority:  normal             |   Milestone:  Unscheduled
Component:  Official binaries  |     Version:  1.6.0      
 Keywords:                     |  
-------------------------------+--------------------------------------------
 Using the attached pickled data file and script I'm reliably getting a
 segfault in numpy.subtract on MacOS X 10.5.8 with a fresh Mac Python 2.7.2
 32-bit from python.org and a fresh install of the official numpy 1.6.0 Mac
 binary.

 The self-test reports no errors (3 known fail, 2 skip, 3179 tests in all).

 Other tid-bits that may be relevant:
  * I started with a larger data file and kept trying different subregions.
 The attached data file is about the smallest subregion I could find that
 showed the problem. Below that the crash went away.
  * If I convert it to float32 I still get the crash.
  * I don't see the crash on MacOS X 10.6.2 using the same python and numpy
 binary installer.
