I did a clean install of the latest svn and ndimage segfaulted on me
when running the tests. I'm keen to see ndimage working, so if anyone
would like to give pointers on how to go about fixing this, I'm happy
to help out. These tests were done on a dual athlon 3800+ with latest
svn versions of numpy and scipy and Python 2.4.3 (#2, Apr 27 2006,
14:43:32)
[GCC 4.0.3 (Ubuntu 4.0.3-1ubuntu5)] on linux2

>>> numpy.__version__
'0.9.9.2786'
>>> scipy.__version__
'0.5.0.2056'


running scipy.test(10, 10) in gdb gives the following:

histogram 1 ... ok
histogram 2
Program received signal SIGSEGV, Segmentation fault.
