Greetings!  I'm happy to announce what I believe to be a good fix for
the issue uncovered by these two examples.  Committed to 2.6.1 and CVS
HEAD.  Will continue to test.  If all goes well I'd like to push out
another stable release at this point.  Of course I may be delayed in
this as Debian uploads are temporarily suspended.

This appears to have fixed the problem.  Thanks!  I can now run the random
tester without irrecoverable failures.  Doing so, I see failures that
are apparently due to a common bug, illustrated by this example:

 (let* ((fn '(lambda (b)
                (declare (type (integer 3352138624 13120037248) b))
                (declare (optimize (speed 3) (safety 1) (space 1)))
                (progn (catch 'ct1
                         (progn (setq b 11159349376)
                                (throw 'ct1 0)))
    (funcall (compile nil fn) 4108962100))

;; should yield 11159349376, but doesn't.

This bug has come up several times in an overnight run (~50K tests
on terms of 'size' 200). See MISC.198 and MISC.199 in ansi-tests/misc.lsp
