As far as I can tell, HJ's patch doesn't work.  Certainly
it didn't change the output for the given test case at all.

I have a different patch that I started some time ago before I
left on vacation that fixes this bug, as well as the variable
sized structure copy bug as seen in execute/20020412-1.c.
