Do you have a simple program that demonstrates the problem? I have an x86 machine with Python 2.3, and an x86_64 machine with Python 2.4 available. I wrote a simple test program which performs a slice operation, but it behaves the same on both platforms.
Here's the program: #------------------------------------------------------------------------ import numarray, sys, os print "python: ", sys.version_info print "numarray:", numarray.__version__ print "CPU: ", os.uname()[-1] n = numarray.arange(10) o = numarray.outerproduct(n,n) p = o[3:7,6:10].copy() q = numarray.outerproduct([3,4,5,6], [6,7,8,9]) print "Success: ", numarray.alltrue(p.ravel() == q.ravel()) #------------------------------------------------------------------------ Here are the two results I gathered: python: (2, 4, 1, 'final', 0) numarray: 1.3.3 CPU: x86_64 Success: True python: (2, 3, 2, 'final', 0) numarray: 0.9 CPU: i686 Success: 1 Jeff
