In this case I'm using the debugger to find out why a particular
function produces an error. I'm instrumenting this top level function
and then stepping through it using "d" to see what's going on, but in
the middle there's, say, a ibus related function call that I know is
incredibly complicated, and also isn't the source of the error. So I'd
like to just hop over that particular ibus call and continue on with the
body of the function. Hope that's a clearer explanation…
