Hi,
From random-integer testing on AMD64.

* (defun foo (a b)
(logbitp 3
(when a
(ash (loop for i below 0 sum 1)
(dotimes (i 1 -5) b)))))
; in: DEFUN FOO
; (SB-INT:NAMED-LAMBDA FOO
; (A B)
; (BLOCK FOO (LOGBITP 3 (WHEN A (ASH # #)))))
;
; caught STYLE-WARNING:
; The variable B is defined but never used.
; (ASH
; (LOOP FOR I BELOW 0
; SUM 1)
; (DOTIMES (I 1 -5) B))

; caught STYLE-WARNING:
; Lisp error during constant folding:
; The function SB-C::ASH-INTO-WORD-MOD is undefined.

full call to SB-C::ASH-INTO-WORD-MOD
This is probably a bug in SBCL itself. (Alternatively, SBCL might
have been
corrupted by bad user code, e.g. by an undefined Lisp operation like
(FMAKUNBOUND 'COMPILE), or by stray pointers from alien code or from
unsafe
Lisp code; or there might be a bug in the OS or hardware that SBCL is
running
on.) If it seems to be a bug in SBCL itself, the maintainers would
like to
know about it. Bug reports are welcome on the SBCL mailing lists,
which you
can find at <http://sbcl.sourceforge.net/>.
