DDD 3.2.1 (i686-pc-linux-gnu) gets `Segmentation fault' signal

[Kannan Moudgalya]

Hi,

I have recently started using ddd (thanks a lot - I really enjoy using
it).  ddd crashed today and it asked me to send you a bug report.  Here it
is - hope it is useful.

Please see attached two source files (test.f and sub.f), edited script of
the session (bugreport) and the log file ~/.ddd/log.  

I did the following:

1.  compile test.f and sub.f using g77 -g test.f sub.f
2.  invoked ddd using ddd a.out &
3.  stepped through the lines of the code in ddd and continued till
    termination
4.  appended sub.f at the end of test.f (as I did this in emacs, this 
    does not appear in the script)
5.  compile it using g77 -g test.f
6.  went to ddd and clicked the following:
    file > open recent > a.out 
7.  it asked whether it should load new symbol table
8.  I answered yes and ddd crashed

I have been using RH6.2.  If you need any other information,
please let me know.  Regards.

Kannan.

      program main
      a = 5
      b = 2
      c = sum(a,b)
      write(*,*)a,b,c
      stop
      end

      function sum(a,b)
      sum = a + b
      return
      end

g77 -g test.f sub.f
test.f: In program `main':
test.f:4: warning:
         c = sum(a,b)
