trace-calls-to-procedure is a low-level trace procedure that returns a trap that you have to install in the trap state. You can either use the add-trap! procedure from (use-modules system vm trap-state), or use the add-trace-at-procedure-call! procedure from the same module.
That said, there seems to be a bug in add-trace-at-procedure-call! which I'm having a hard time figuring out... c'est la vie.
