just to report something positive with my (almost;-) daily build on 64Bit:
With '0.5.0.2012' **all** tests pass on 64 Bit (apart from the well-known ndimage one).
Best, Arnd

On 32 bit there is still one failure but I cannot reproduce it on a 64 bit system. Why ?
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.

Travis, Here is the output of mycobyla.py 32bit: Linux amanda 2.6.11.4-21.12-default #1 Wed May 10 09:38:20 UTC 2006 i686 athlon i386 GNU/Linux Result by cobyla with one constraint [ 4.95535574 0.66667043] Result by cobyla with two constraints [ 4.957975 0.64690335] Exact results [ 4.95535625 0.66666667] 64bit: Linux lisa 2.6.13-15.10-default #1 Fri May 12 16:13:03 UTC 2006 x86_64 x86_64 x86_64 GNU/Linux Result by cobyla with one constraint [ 4.95535574 0.66667043] Result by cobyla with two constraints [ 4.95535778 0.6666553 ] Exact results [ 4.95535625 0.66666667] So, the difference in the results is associated with the constraints.
