If the function is tail-recursive, it is normally compiled as such and
there are no recursive calls to trace!  Maybe that's your problem.
Tail recursion compiling can be turned off.  The other trick is to
put in a useless statement that renders it non-tail-recursive to
force it to compile that way.
