Juan,
compiling a file containing:
(defun bar ()
(labels ((rec (x)
(rec x)))))
(defun foo ()
(labels ((rec (x)
(rec x)))))
yields:
$ ecl.exe -eval '(compile-file "../foo.lisp")' -eval '(si:quit)'
;;; Loading #P"d:/usr/src/ecl-bin/cmp.fas"
;;;
;;; Compiling ../foo.lisp.
;;; OPTIMIZE levels: Safety=2, Space=0, Speed=3, Debug=0
;;;
;;; Compiling (DEFUN BAR ...).
;;; Compiling (DEFUN FOO ...).
;;; Internal error:
;;; in file foo.lisp, position 53
;;; at (DEFUN FOO ...)
;;; ** C-STACK overflow at size 557056. Stack can probably be resized.
Experimentation tells that following conditions must hold for the error
to manifest itself:
- the names of the functions established by LABELS must coincide
- the bodies of the functions established by LABELS function bodies
must be the same
Attaching GDB reveals:
