On my present machine it is an AMD Sempron, but I had the same problem
with other AMDs like AlthonXP and Duron. It is not very clear for me
_what_ binary you mean. The specfun.pyd? I have no means of determining
what version it has (I found version "0.0" in the crash report, but I
guess that would be of no help) . Python itself and any function in
scipy/numpy/ETS etc. works fine on all processors.
My scipy install is from the scipy-0.6.0.0004_s-py2.5-win32.egg (which
is not marked as exclusively built for Intel), but I found the same
behaviour in earlier versions.

Where do I find this PII version you mentioned?
