[Bug fortran/13940] New: [gfortran] F77 code accepted by g77 causes ICE in gfortran

["bdavis9659 at comcast dot net" <gcc-bugzilla at gcc dot gnu dot org>]

The subroutine listed below causes an ICE in gfortran.  Compiles OK with
g77.

No declaration is made as to the "standard comforming" status of this code, only
that it is accepted by g77 ( and by SEL/GOULD FORT77)

$ cat dmubar.F
      SUBROUTINE DMUBAR
      INTEGER*4 DMUNDTAB(25)
      DATA DMUNDTAB            /X'40000000',X'20000000',X'10000000',
     &               X'08000000',X'04000000',X'02000000',X'01000000',
     &               X'00800000',X'00400000',X'00200000',X'00100000',
     &               X'00080000',X'00040000',X'00020000',X'00010000',

     &               X'00000080',X'00000040'/
      II = DMUNDTAB(I)
      RETURN
      END
