Well, I am trying to get with handler-bind, however, it still prints nothing at all (for the backtrace, I mean)

(defun handle-any-error-log (e)
  (print "x") ; checking that we are indeed in the handler
  (with-open-file (eout "errors.txt"
            :direction :output)
    (format eout "Unhandled error detected: ~%")
    (format eout "~A~%" e)
    (format eout "Backtrace: ~%")
    (loop for x from (si::ihs-top)
       to 0 do
     (format eout "~A~%" (si::ihs-fun x)))
    (format eout "~%")))

(eval-when (:load-toplevel :execute)
  (handler-bind
      ((error #'handle-any-error-log))
    (post-initialization)))


Output:

enerccio@G73Jh-Arch:~/projects/gaia/gaia$ cat errors.txt
Unhandled error detected:
LOAD: Could not load file #P"/media/home/home/enerccio/projects/gaia/gaia/plugins/crap.fas" (Error: "/media/home/home/enerccio/projects/gaia/gaia/plugins/crap.fas: file too short")
Backtrace:

In CL you usually can't get stack trace "out of condition".

Usually you can get the current stack trace. I.e. before stack is unwound.
I.e. catching error handler-bind you can get stack trace, because you are still
inside the stack, but for example with handler-case you are invoked after
the stack is unwound.

PS. also check out trivial-backtrace if you want be portable library, although
I don't know if it supports ECL.
