I have traced down the bug, it was related to an array being altered
inplace instead of copied.
I have also taken out two other bugs related to C long (and Python int)
being 32 bit on Windows 64.
I still get four fails on Win 64. They are there in Patrick's code as
well, so they are related to his coding.
An update is commited here:
