+314: "LOOP :INITIALLY clauses and scope of initializers"
+ reported by Bruno Haible sbcl-devel "various SBCL bugs" from CLISP
+ test suite, originally by Thomas F. Burdick.
+ ;; <http://www.lisp.org/HyperSpec/Body/sec_6-1-7-2.html>
+ ;; According to the HyperSpec 6.1.2.1.4, in for-as-equals-then, var is
+ ;; initialized to the result of evaluating form1. 6.1.7.2 says that
+ ;; initially clauses are evaluated in the loop prologue, which precedes all
+ ;; loop code except for the initial settings provided by with, for, or as.
+ (loop :for x = 0 :then (1+ x)
+ :for y = (1+ x) :then (ash y 1)
+ :for z :across #(1 3 9 27 81 243)
+ :for w = (+ x y z)
+ :initially (assert (zerop x)) :initially (assert (= 2 w))

+315: "no bounds check for access to displaced array"
+ reported by Bruno Haible sbcl-devel "various SBCL bugs" from CLISP
+ test suite.
+ (locally (declare (optimize (safety 3) (speed 0)))
+ (let* ((x (make-array 10 :fill-pointer 4 :element-type 'character
+ :initial-element #\space :adjustable t))
+ (y (make-array 10 :fill-pointer 4 :element-type 'character
+ :displaced-to x)))
+ (adjust-array x '(5))
+ (char y 5)))
+
+ SBCL 0.8.10 elides the bounds check somewhere along the line, and
+ returns #\Nul (where an error would be much preferable, since a test
+ of that form but with (setf (char y 5) #\Space) potentially corrupts
+ the heap and certainly confuses the world if that string is used by
+ C code.
+
+316: "SHIFTF and multiple values"
+ reported by Bruno Haible sbcl-devel "various SBCL bugs" from CLISP
+ test suite.
+ (shiftf (values x y) (values y x))
+ gives an error in sbcl-0.8.10.
+
+ Parts of the explanation of SHIFTF in ANSI CL talk about multiple
+ store variables, and the X3J13 vote
+ SETF-MULTIPLE-STORE-VARIABLES:ALLOW also says that SHIFTF should
+ support multiple value places.
+
+317: "FORMAT of floating point numbers"
+ reported by Bruno Haible sbcl-devel "various SBCL bugs" from CLISP
+ test suite.
+ (format nil "~1F" 10) => "0." ; "10." expected
+ (format nil "~0F" 10) => "0." ; "10." expected
+ (format nil "~2F" 1234567.1) => "1000000." ; "1234567." expected
+ it would be nice if whatever fixed this also untangled the two
+ competing implementations of floating point printing (Steele and
+ White, and Burger and Dybvig) present in src/code/print.lisp
+
+318: "stack overflow in compiler warning with redefined class"
+ reported by Bruno Haible sbcl-devel "various SBCL bugs" from CLISP
+ test suite.
+ (setq *print-pretty* nil)
+ (defstruct foo a)
+ (setf (find-class 'foo) nil)
+ (defstruct foo slot-1)
+ gives
+ ...#<SB-KERNEL:STRUCTURE-CLASSOID #<SB-KERNEL:STRUCTURE-CLASSOID #<SB-KERNEL:STRUCTURE-CLASSOID #<SB-KERNEL:STRUCTUREControl stack guard page temporarily disabled: proceed with caution
+ (it's not really clear what it should give: is (SETF FIND-CLASS)
+ meant to be enough to delete structure classes from the system?
+ Giving a stack overflow is definitely suboptimal, though.)
+
+319: "backquote with comma inside array"
+ reported by Bruno Haible sbcl-devel "various SBCL bugs" from CLISP
+ test suite.
+ (read-from-string "`#1A(1 2 ,(+ 2 2) 4)")
+ gives
+ #(1 2 ((SB-IMPL::|,|) + 2 2) 4)
+ which probably isn't intentional.
+

+ (defclass foo85a () ((size :initarg :size :initform 2) (other)))
+ (slot-value i 'size))
+ (list value (type-of condition)))
+ should return (1 NULL) but returns (2 NULL) in sbcl-0.8.10. See
+ ensuing discussion sbcl-devel for how to deal with this.
+
+321: "DEFINE-METHOD-COMBINATION lambda list parsing"
+ reported by Bruno Haible sbcl-devel "various SBCL bugs" from CLISP
+ test suite.
+ (define-method-combination w-args ()
+ ((method-list *))
+ (:arguments arg1 arg2 &aux (extra :extra))
+ `(progn ,@(mapcar (lambda (method) `(call-method ,method)) method-list)))
