In amode 31, the 'high-order' bit is always cleared by LA. You often see code where that is the only purpose of the instruction. He's correctly going amode 24, but if GET tries to access memory above the line, or return to an above the line caller, you get trouble. GET was changed a while back to allow amode 31 callers, he can probably just get rid of the logic to go amode 24.
