[chuck-users] functions returning arrays

[Colin Sullivan]

David,

I think the problem may be that you are returning an array that is local to
your function and it is getting deallocated when the function returns.

If you used the same syntax to instead return an object's member variable
which is an array, I think it would work as expected.

Hope that helps.
