DDD 3.2.91 (i686-pc-linux-gnu) gets `Segmentation fault' signal

[Doug Owens]

Hi,

I am trying to debug a shared library buildt with symbols that is loaded
by an application that was built without symbols.  The application is
started by a script that sets envirionment variables and other things. 
I have included the script as an attachment.  The script reads an
environment variable called DEBUGGER which I have set to "ddd" and
launches ddd with the application as its only argument. e.g.
'DEBUGGER=ddd ./cwide'.

The ddd start-up window displays and then I get:
 "Internal error (Segmentation fault).

 Oops!  You have found a bug in DDD.

 If you can reproduce this bug, please send a bug report
 to <bug-ddd@gnu.org>, giving a subject like

     DDD 3.2.91 (i686-pc-linux-gnu) gets `Segmentation fault' signal

 To enable us to fix the bug, you should include the following
information:
 * What you were doing to get this message.  Report all the facts.
 * The contents of the `~/.ddd/log' file as generated by this session.
 Please read also the section "Reporting Bugs" in the DDD manual.

 We thank you for your support."

This happens regardless if I have a .ddd preference folder in my home
directory or not.

I am running Redhat Linux 6.2 with GNOME GTK as my window manager.  I
have Open Motif 2.1 installed.  I also tried to use version 3.4 of ddd
from a prebuilt rpm, with the same result.  I built 3.2.91 with gcc
2.95.2.

Please let me know if I can give you any additional information.

Sincerely,
Doug Owens
