DDD bug -- Very short Fortran program


From: Fred Krogh
Subject: DDD bug -- Very short Fortran program
Date: Thu, 16 Feb 2006 15:32:15 -0800
User-agent: Mail/News 1.5 (X11/20060206)

Here is the program.

c Program to show problem in ddd
      integer I, IA(5)
      call sub1(IA)
      print *, (IA(I), I = 1, 5)
      stop
      end
      subroutine sub1(II)
      integer I, II(*)
      do 10 I = 1, 5
        II(I) = I
 10   continue
      return
      end

To see the bug run the code and stop on the return second line from the
bottom.
Move the cursor over the array name II.  DDD then crashes.

Note that I have had the same problem using lesstif in place of motif,
and have had this problem for more than two years with frequent updates
as provided by gentoo.

Thanks,
    Fred
