To make things reproducible, I've put all my packages in this repository:

Actually, I made a mistake --- the one in
drive_c/windows/system32/msvcr90.dll does not work for me.
The one I use is installed by the Python installer (as I found out)
and it is in:

drive_c/windows/winsxs/x86_Microsoft.VC90.CRT_1fc8b3b9a1e18e3b_9.0.21022.8_x-ww_d08d0375/msvcr90.dll

Which seems to be the same as the one that you use. Just in case, I've
put it here:

https://github.com/certik/numpy-vendor/blob/master/msvcr90.dll

This however is a big problem. I've tested it on the actual Windows
64bit XP box, and the test simply segfaults at this place.
Ralf, I should note, that your latest scipy RC tests also segfault on
my Windows machine, so maybe something is wrong with the machine...
