I don't know.  I looked at it a bit, but couldn't see anything obvious.

But, since you have access to both systems you are in a great position 
to figure out why it is failing on 32-bit systems.   Insert some 
print-statements in the fmin_cobyla code (the calcfc function might be a 
good place) and compare the outputs on the two systems when you run just 
that test. 

It would be great if you could help track it down.
