Hi Barry,

Perhaps there is some kind of misunderstanding?  M-x gud-gdb seems to
produce a prompt for gdb (have to remember not to use -i=mi for that one),
and it provides some simple support for setting breakpoints and printing
variables via the C-x C-a C-b / M-x gud-break sort of commands, but this
seems to be barely better than simpling running in a terminal.  There seems
to be no graphical representation of the point of execution, the location
of breakpoints either within the buffer or in a special breakpoint buffer,
nor a backtrace buffer, or the list of local variables (which is the only
one that I never really found very useful).

But, yes, using gud-gdb does not show the same behavior where a C-c C-c
will make the M-x gud-<something> commands stop working.  In some sense it
does indeed work better, but I have fond memories of a time where I think
that the GDB interface in Emacs was working.  Is there at least of
confirmation that others are seeing the same issue with things like M-x
gud-print stop working with M-x gdb?  I was troubleshooting with someone on
Reddit and they never saw this issue.

Zach
