Which, of course, is the logically correct way to do it. I guess I just
read too much into the suggestion in the manual to jump to the
"unused" Data Error exception vector under some miss conditions.
I tried to eliminate the immediate error fault that was going to
happen, but I guess we have to force that fault to get the proper
information in the fault registers.
