[j-devel] RETURN treated incorrectly in compiled code

[Robert D. <rob...@ya...>]

Hello,

While testing Maxima + ABCL I encountered the following bug ...
consider:

(defun f (x)
  (prog (y z)
        ((lambda (u)
           (if (< x 0) (return nil))) nil) (return t)))

When interpreted, (f -1) => NIL.
When compiled, (f -1) => T.
I'm pretty sure the result (f -1) => T is incorrect.

For the record, with Clisp (compiled or interpreted),
I get (f -1) => NIL.

FWIW.

Robert
