Segmentation fault in DDD and Cygwin 1.3.10

Subject: Segmentation fault in DDD and Cygwin 1.3.10

HI,
        I have downloaded and installed the latest CYGWIN 1.3.10
(complete), and installed Xfree for Cygwin. I am however having trouble
running DDD. I have downloaded the latest version 3.3.1, and compile as
the manual suggests, DDD compiles fine, but will not run properly.

        First lets get some details you ask for out of the way

        running 'ddd --configuration' reports

Copyright (C) 1995-1999 Technische Universit채t Braunschweig, Germany.
Copyright (C) 1999-2001 Universit채t Passau, Germany.

Compiled with GCC 2.95.3-5 (cygwin special), libstdc++ 2.8.0
Requires X11R6, Xt11R6, Motif 2.1 (GNU/LessTif Version 2.1 Release

        GDB is GNU gdb 5.0 (20010428-3).

        I have lesstif-cygwin-0.93.18 installed.

        DDD Compiles with no warnings or errors out of the box, and
installs OK. However when I try and run it, the main window appears and
then I get an internal error warning, and segmentation fault error
message. As a test I disabled the 'tip of the day' in Ddd, then I dont
get the segmentation fault until I try and open a file.

What am I doing wrong? I have read the FAQs and think I have checked all
the version numbers etc.

Please help.

Thanks
Ian
