Description

Reported by Brian Mastenbrook:

When attempting to GO to a tag whose dynamic extent has ended, ABCL quits and prints the name of the exception used for internally handling GO (org.armedbear.lisp.Go). I see the same behavior in compiled or interpreted code.

CL-USER(1): (lisp-implementation-version)
"0.16.0"
CL-USER(2): (let ((f nil)) (tagbody (setf f (lambda () (go foo))) foo)  
(funcall f))
org.armedbear.lisp.Go
abcl-src-0.16.0 chandler$

Tentative fix committed in #63.

It would be nice for a review from other developers.

I meant "Tentatively fixed in r12153"

Resolution: → fixed
Status: accepted → closed

Further work by Erik culminating in r12177 made r12153 the wrong solution. Now, non-local transfers of control are properly recognized by both the interpreter and compiler raising errors so this should "never happen".

closed is not 'unscheduled'; moving to the most recently closed milestone.
