C Subject: g77 crashes compiling Dungeon

C The following small segment of Dungeon (the adventure that became the 

C commercial hit Zork) causes an internal error in f771.  The platform is 

C i586-pc-linux-gnulibc1, the compiler is egcs-ss-970821 (g77-GNU Fortran 

C 0.5.21-19970811)

C Here's the FORTRAN code, it's basically a single subroutine from subr.f 

C in the Dungeon source, slightly altered (the original calls RAN(), which 

C doesn't exist in the g77 runtime)

C 

C RND - Return a random integer mod n

C

      INTEGER FUNCTION RND (N)

      IMPLICIT INTEGER (A-Z)

      REAL RAND

      COMMON /SEED/ RNSEED

      RND = RAND(RNSEED)*FLOAT(N)

      RETURN

      END
