hello,
I am trying to get a guile script that is executed on a port server
to display a backtrace if there is an error. as of now I have:
(define (backtrace-test args)
(catch
'ignore
(lambda ()
(lazy-catch
#t
(lambda () (throw 'test-error))
(lambda (key . args)
(let ((stack (make-stack #t)))
(throw 'ignore
(with-output-to-string
(lambda ()
(display-backtrace stack (current-output-port)))))))))
(lambda (k . v)
(display (car v)))))
which, if you run in interactive Guile, displays the backtrace without
complaint. however, when you execute this from the command line, it
says,
Exception during displaying of backtrace: wrong-type-arg
why is this? any help is greatly appreciated.
Thanks,
Erica
