in Guile 3.0.5 installed with Guix (as a package manager on top of
Ubuntu)
In a file I have this simple procedure
(define (f n)
(if (< n 3)
n
(+ (f (- n 1))
(* 2 (f (- n 2)))
(* 3 (f (- n 3))))))
it's a variation of the one calculating the Fibonacci numbers, from an
exercise of the SICP (1.11)
At the REPL, I load the file normally
scheme@(guile-user)> (load "1.11.scm")
Now, I can trace this procedure
scheme@(guile-user)> ,trace (f 4)
trace: | (f 4)
trace: | | (f 3)
trace: | | | (f 2)
trace: | | | 2
trace: | | | (f 1)
trace: | | | 1
trace: | | | (f 0)
trace: | | | 0
trace: | | 4
trace: | | (f 2)
trace: | | 2
trace: | | (f 1)
trace: | | 1
trace: | 11
But I can't tracepoint it
scheme@(guile-user)> ,tp f
Trap 0: Tracepoint at #<procedure f (n)>.
scheme@(guile-user)> (f 4)
Trap 0: (f 4)
Trap 0: | (f 3)
Trap 0: | | (f 2)
ice-9/boot-9.scm:1669:16: In procedure raise-exception:
Wrong number of arguments to #<procedure return-handler (frame depth
values)>
Entering a new prompt. Type `,bt' for a backtrace or `,q' to continue.
scheme@(guile-user) [1]>
and now I can't even print a backtrace
scheme@(guile-user)> (f 4)
Trap 0: (f 4)
Trap 0: | (f 3)
Trap 0: | | (f 2)

and now I can't even trace no more

While executing meta-command:
Wrong number of arguments to #<procedure return-handler (frame depth
