At this point, you should be able to type "bt" to get a backtrace. You
can move up and down through the frames by typing "up" and "down" or you
can jump to the 23rd frame with "fr 23". Once you are in a frame, you
can examine all of the local variables. The first few frames will
probably be non-lilypond code, so you'll want to ignore them.
