Select a frame.
Press "s"
press "c" in the new backtrace.
It should appears Source code location not known in the echo area.

I can reproduce this problem (but adding the debug-on-entry to
backtrace-goto-source just makes things more confusing).
The problem seems to be that
(nth (backtrace-get-index) backtrace-frames)
returns a frame without a :source-available entry here:
(defun backtrace-goto-source ()
"If its location is known, jump to the source code for the frame at point."
(interactive)
(let* ((index (or (backtrace-get-index) (user-error "Not in a stack frame")))
(frame (nth index backtrace-frames))
(source-available (plist-get (backtrace-frame-flags frame)
:source-available)))
(unless (and source-available
(run-hook-with-args-until-success
'backtrace-goto-source-functions))
(user-error "Source code location not known"))))
I'm pretty unfamiliar with backtrace.el, but I can't see that slot being
added anywhere there? edebug does add it, but isn't involved in any way
here. So it looks like something has gotten lost over the years?
However, `RET' on a symbol finds the sounds just fine, which is probably
why nobody has noticed this problem. I.e., nobody's using the `s'
command in *Backtrace* buffers.

The `s' command is introduced in Emacs 27.1 -- and doesn't work there,
so it looks like it's never actually worked?

The `s' command is only meaningful when called from edebug, so I've now
rejiggered the code and removed the `s' binding from backtrace-mode-map
in Emacs 29.

What documentation are you referring to?

Hem... Sorry again, the documentation for s command in the debugger
section of the manual is not anymore in the elisp manual on master,
atleast.
