Hi everybody, As I (and others) already mentioned in this mailing list, there is a python crash (like an exit) when we use scipy under windows for a simple operation like : from scipy import * a = zeros(300000,typecode='F') c=a*a Analyzing the scipy source code, it seems to come from the fastumath module : I comment every line that import fastumath and it works !!! Is anyone have an idea to solve this problem with fastumath under windows ? Thanks. O.R.

Does it just happen with typecode 'F'? Does it just happen with multiplication? Does it just happen after a certain array size? It is just happening with windows, right? -Travis

no but even with typecode 'D'
Does it just happen with multiplication?
No but for every operation on an array
Does it just happen after a certain array size?
Yes. The limit value is 258168
It is just happening with windows, right?
yes.
