One option that would help me (and probably countless others) to debug 
legacy code is an -fcheck-size option.

The meaning of this option would be:

         Check if array references fall within the extent of the array.

E.g.

         REAL A(10,10)
         A = 1.0
         CALL SUB(A,10)
         END
         SUBROUTINE SUB(A, N)
         REAL A(N, N)
         PRINT*,A(1,N*N)
         END

Kind regards,
