Create a trivial C program.  Here's a good example:

    int main()
      return 0;

Save it as foo.c, and compile it with debugging:

    gcc -ggdb3 -o foo foo.c

>From emacs -Q, start gdb on foo:

    M-x gud-gdb RET 

In my case, since foo is the only executable in the dir, the command
line for gdb is already set up correctly as:

    gdb --fullname foo

Hit RET.  You should be at the gdb prompt.  Start the program:

    start RET

You should now get another window with foo.c in it for context.  Switch
to that buffer and type RET.

    C-x o

In my case, I get:

    comint-send-input: Current buffer has no process

This is new and broken behavior.  The expected behavior is that a
newline is inserted in the buffer.

AFAICT the fringe handling is a separate issue because those bindings
are only placed in the `gud-minor-mode-map`, so the inheritance from
`gud-mode-map` doesn't affect those.

I just pushed a patch which introduces a new map to share the menu
between the two keymaps so `gud-minor-mode-map` doesn't (need to)
inherit from `gud-mode-map` any more.

This should fix the problem (which was also labeled bug#61162 and bug#61271).
