I'm not a gdb expert, but I think you could waste a lot of time and get 
nowhere here. In principle, you can create watchpoints for all your 
variables. You could then add all your variables to the auto display 
list ('display'). You could then define 'hook-stop' to automatically 
restart (put a 'continue' in there) every time gdb stops. This would 
automate collection and display, but you then have the problem that you 
have to set new watchpoints for every new scope, and they're 
automatically deleted when they go out of scope.

This should be handled with tracepoints, but I don't think you'll do any 
better with them; they don't seem to be completely implemented yet.
