Others have pointed out the likely reason that you are getting stack
overflows and how to work around that.
Let me just note that the above statement about being the same type is
incorrect. There is no requirement even vaguely related to that. All the
arrays must be the same shape (well, I assume there's a requirement like
that; didn't bother to check, but it sure seems like there would be).
But type isn't an issue.
P.S. I might also note that it seems pretty darned inefficient for the
compiler to create a temporary array for something quite that simple.
For more complicated cases. It suggests to me that the compiler isn't
paying much attention to the efficiency of WHERE statements. Perhaps it
wasn't very high on their priority list.
