numpy bug

after a while trying to find the legal manner to file numpy bug reports,
since it's a simple one, I thought maybe a first step is to describe the bug 
here. Then maybe someone will direct me to the right channel.

So, numpy appears not to correctly compute bitwise_and.reduce and 
bitwise_or.reduce : instead of reducing over the complete axis, these methods 
only take the extremities into account. Illustration :

 >>> from numpy import *
 >>> bitwise_or.reduce(array([8,256,32,8]))
8
 >>> import numpy
 >>> numpy.__version__
'0.9.8'
 >>>

Platform : Win XP SP2, Python 2.4.2
