Hi Steve,

OK on the above extra change passing the array slice, I got as far as 
realizing that any of the off the end elements would get picked as they 
are zero but missed that maxloc() returns an index that is 1 based.

We are not there yet on Windows either:

with a bad decode still appearing and other small differences. Could 
this be down to pseudo RNG differences?

I will try and work out what is happening on OS X.
