#571: merging rest-parameter in combination with inlining fails
----------------------+-----------------------------------------------------
Reporter: felix | Owner: felix
Type: defect | Status: new
Priority: critical | Milestone: 4.7.0
Component: compiler | Version: 4.6.x

----------------------+-----------------------------------------------------
The following code causes a compile-time error. Somehow the calls to
`fail` are incorrectly modified for rest-parameter merging. The output
should be "UNBOUND VARIABLE: (foo)", but it is "UNBOUND VARIABLE: foo".
This happens with "-O1 -inline".
(define (lisp-eval x a bt)
(fail bt "UNBOUND VARIABLE" x))
(define (lisp-apply fun args a bt)
(let ((hd (car fun)))
(case hd
((label)
(if (= (length fun) 3)
(let ((fo (caddr fun)))
(lisp-apply fo args (cons (cons (cadr fun) fo) a) bt))
(fail bt "INVALID LABEL FORM" fun)))
(else (lisp-apply (lisp-eval fun a bt) args a bt)))))
(define (error-hook bt msg args)
(error msg args))
(define (fail bt msg . args)
(error-hook bt msg args))
(lisp-eval 'foo '() '())
