Hi-
I created the following file, which I ran under guile-2.0 and master.
There is no tracing output. What am I misunderstanding?
(use-modules 
(system vm trace)) 

(define (write-hi) 
(write "hi")) 

(define (outer) 
(write-hi)) 

(trace-calls-to-procedure write-hi) 
(trace-calls-in-procedure write-hi) 
(trace-instructions-in-procedure write-hi) 
(outer) 

Thanks,
Mike Gran

Weird.  From an initial glance I don't know why this isn't working.
Irritating!

The various trace commands create VM traps that you have to install to 
the thread-local trap state. See API Reference/Debugging/Traps/Trap 
States in the  manual.
