This is the result of installing two of Taiichi's fixes: > (random 0) Error: 0 is not of type (SATISFIES PLUSP). Error signalled by RANDOM. > (print 'print-is-messed-up) PRINT-IS-MESSED-UP Error: Signal 4 caught. The internal memory may be broken. You should check the signal and exit from Lisp. Anyone else had this problem? - Eliot
