The default behaviour for gdb in Emacs has changed considerably since 21.3.
You could read the manual to understand these differences. It says
(GDB Graphical Interface):

Text command mode refers to the mode used in 21.3. The default mode for
22.1 is referred to as graphical mode and uses "gdb --annotate=3".
When your gdb sessions are independent, you can always uses separate Emacs
sessions, of course.
