I remember (in 1974) submitting a PL/1 program to the IBM checkout
compiler, which ran using up my complete cpu time quota and produced no
output at all. I resubmitted it to the optimising compiler which used a
couple of seconds and said “Mismatched quotes”. 

I’d missed out a close quote early in the program, so all my program code
had disappeared into literal text, and all my output messages and error
texts had become program. The checkout compiler had had a fit trying to
turn the messages into valid PL/1 program!
