  10 C The following small segment of Dungeon (the adventure that became the
  11 C commercial hit Zork) causes an internal error in f771.  The platform is
  12 C i586-pc-linux-gnulibc1, the compiler is egcs-ss-970821 (g77-GNU Fortran

  30 C Here's the FORTRAN code, it's basically a single subroutine from subr.f
  31 C in the Dungeon source, slightly altered (the original calls RAN(), which
  32 C doesn't exist in the g77 runtime)
