        w[here]|bt|backtrace        Display stack frames.

        Print the entire stack frame. Each frame is numbered; the most recent
        frame is 0. A frame number can be referred to in the "frame" command;
        "up" and "down" add or subtract respectively to frame numbers shown.
        The position of the current frame is marked with -->. C-frames hang
        from their most immediate Ruby frame to indicate that they are not
        navigable.
