problem with ddd-test-3.3.12-test4cvs

[David Relson]

Hi,

As I'm new to ddd some of the problems I'm experiencing _may_ be my
fault.  However, as I've been writing software for decades and using
gdb on and off for 20 or so years, I suspect there's a problem in the
ddd/gdb interaction.  In any case, I'll describe what's happening as
best I can.

I've built ddd-test-3.3.12-text4cvs from source on my Mandriva 2006.0
workstation with kernel 2.6.14.2 and gcc 4.0.1.  To simplify the test
environment, I've typed in "hello.c" and run "make hello" (which ran
"gcc -g hello.c -o hello.c") to generate an executable.  The executable
runs fine from the command line and "gdb hello" works fine.

However, "ddd hello" reports

   DDD: Debugger Terminated
   GDB terminated abnormally (Segmentation fault)
   <Restart GDB>  <Exit>  <Help>

and generates a core dump of gdb.

Using "gdb /usr/bin/gdb core.15284" to look at the core dump, gdb
reports:

### After exiting gdb, I tried running the indicated command and got:

address@hidden ddd]$ gdb -q -fullname hello

Program exited normally.

Let me know if there's additional info that would help.
