Looks as if my earlier bug report hasn't appeared (the other bug was why 
I was trying --annotate)
If I run with -i=mi I get lots of

    mi_cmd_stack_info_frame: No arguments required
messages. Also if I try turning on tooltips when I hold the mouse over a 
variable I get the message

    error in process filter: Args out of range: "", 0, -1
There's also a longish wait on startup when it is turning off non stop mode
and I see the message there
    No symbol "non" in current context.
in the gdb buffer, I don't know if that is expected?

If I then do a quit in the debugger I also get the message about the 
process not running.
