bug#4200: 23.1.50; gdb mode screwup when setting breakpoint

[Miles Bader]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


   (1) start emacs, with -Q

   (2) start gdb on an executable in the current dir; let's say it's
       called "foo", and is the most recent excutable in that dir, so
       gdb chooses it by default:

         M-x gdb RET

   (3) split the current window:

         C-x 2

   (3) Visit the source file containing the "main" function, and move to
       some source line in that function:

         C-x C-f foo.c RET
         C-n ...

   (4) Set a breakpoint on that line:

         C-x SPC

   (5) **** Note that the "(gdb) " prompt in the *gud-foo* buffer has
       disappeared!  Weird... but let's continue

   (6) Select the other window, where the *gud-foo* buffer is:

         C-x o

   (7) Try to run the program, even though the prompt is gone:

         run RET

   (8) **** The following error messages are given (these lines are from
       the *Messages* buffer):

         error in process filter: gdb-starting: Unexpected `starting' annotation
         error in process filter: Unexpected `starting' annotation

       Also note that for some reason, the "run" command caused a
       breakpoint list to be displayed in the *gud-foo* buffer, and that
       now there's a prompt again!

   (9) Try to run again, using "run RET"; this time it works (after you
       answer "y" to the gdb query), and correctly stops at the
       breakpoint you set.


Thanks,

bug#4200: 23.1.50; gdb mode screwup when setting breakpoint

`gdb-starting' from gdb-mi.el in Emacs trunk doesn't contain such code.
Looks like somehow `M-x gdb' launched old GDB UI in your Emacs.

Can you not replicate it?  I was using the trunk as of a few days ago.

 Do I need to use anything more than "emacs -Q" to test this?

Thanks,
