A simple tool you can use is the 'racket/trace' library:
http://docs.racket-lang.org/reference/debugging.html
It'll make the execution of a function visible to you. You have to
explicitly trace the function you want to watch.

There's also an "errortrace" module that can help produce stack traces:
http://docs.racket-lang.org/errortrace/using-errortrace.html
You need to do a little work to hook it into your program. For an
example, see the very top startup script of Eric Hanchrow's rudybot:
https://github.com/offby1/rudybot/blob/master/freenode-main.rkt
where you'll see that it has the line:
exec racket -l errortrace --require "$0" --main -- ${1+"$@"}
at the top: that's one way to hook errortrace in.
