I can get a core dump off it too, sometimes. The problem is in
ExecEvalArray, which computes the dimension of the result as [1:2]
even though there are no elements to put in it.
Joe, what do you think about this? Offhand I think that the only
workable definition is that this case yields another zero-dimensional
array, but maybe there is another choice?
We should probably check all the other array operations to see if they
have comparable problems.
