Mmh, is the script I included in the previous mail not enough?  It
passes on 32-bits but fails on 64.  Here it is again (let me know if
you want something different):

#!/usr/bin/env python
import numpy as N
from scipy.weave import inline

vec = N.rand(100)

code = """
double sum = 0.0;
int npts = Nvec[0];
for (int i=0;i<npts;++i) {
   sum += vec[i];
}
return_val = sum;
"""

print inline(code,['vec'])
print vec.sum()

# EOF

Thanks,

f
