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?
Sorry for the slow response -- I'm at the airport just heading home from a marathon 30 day business trip.
I think producing another zero-dimensional result is the only way that makes sense unless/until we change multidimensional arrays to really be arrays of array-datatype elements. Right now they're two different things.
We should probably check all the other array operations to see if they have comparable problems.
Yes -- I'll see if I can find the time over the next couple weeks while home.
