When a run-time error occurs, some programs print an error message (with a line number), followed by a call trace which lists the sequence of pending subroutine calls at the time the error occurred. For example, we might have: Zero divide error in line 12 in procedure "Whos On First" Called from line 34 in procedure "Whats on Second" Called from line 56 in procedure "IDont Knows On Third" Called from line 78 in procedure "Bud And Lou" Explain what would have to be done to include a call trace (with line numbers) in the code generated by a compiler. Since run-time errors are rare, the solution you adopt should impose little, if any, cost on ordinary calls. All the expense should be borne after the run-time error occurs.
