Hello Previously, handling of compiler-note in call-with-compilation-hooks was commented out. It isn't now, and I'm getting a host of uninteresting "Closure XXX will be stack allocated" notes and nothing else. Since compiler-note is defined as (or excl::compiler-note compiler::compiler-note) neither of which is public I wonder if it's intended to be handled by the user. I have this in my .swank.lisp for now: #+allegro ;;; Silence those notes on allegro. (defun swank-backend::compiler-note-p (object) (declare (ignore object)) nil) Cheers, Gabor
