Description (last modified by gb)

The following transcript suggests the presence of a new bug in the CCL compiler in the vicinity of subtypep. Probably part of a disagreement about when (values ...) can be used in a type expression. Something like this just broke an ACL2 rebuild that didn't break yesterday.

% ccl -n
Welcome to Clozure Common Lisp Version 1.4-dev-r12509M-trunk  (LinuxX8664)!
? (defvar x)
? (defvar y)
? (defun foo () x)
? (defun bar () y)
? (proclaim '(ftype (function () (values t)) foo bar))
? (defun fap () (- (foo) (bar)))
> Error: VALUES type illegal in this context:

> While executing: (:INTERNAL CCL::NX1-COMPILE-LAMBDA), in process listener(1).
> Type :GO to continue, :POP to abort, :R for a list of available restarts.
