Using Emacs 23.0.0.1 and GNU gdb 6.6-debian I have problems running gud.

GDB produces the attached output.

Emacs fails to parse all the annotations and says things like:
"
error in process filter: gdb-display-source-buffer: Wrong type
argument: stringp, nil
error in process filter: Wrong type argument: stringp, nil
"

It also fails to open the source code frame.

As a workaround, If I manually open a new frame, I can switch to the
source code buffer (which has been successfully loaded in the
background).  If I then do "f" in the GDB buffer, the source code
frame gets the current execution position highlighted and I'm back to
where I would have been with Emacs 21.

Please tell me if you need any more information to be able to reproduce this.

  Regards //Johan
