A short wrestle with a debugger on a Sun3/60 shows that it is strcpy()
that dies. The buggy code can be found early in main():

:  /* if the user has set an environment variable "TETRIS" then process it */
:
:  if(argc<2 && getenv("TETRIS") == NULL) {
:    [ ... ]
:    strcpy(tetrisenv, getenv("TETRIS"));

Just change '==' to '!=' -- 15th commandment: thou shalt not invoke strcpy()
with a NULL source string.
