MERGE also have the same problem.
c: (COERCE 'AND 'FUNCTION) returns something related to
(MACRO-FUNCTION 'AND), but ANSI says it should raise an error.
- g: (LOAD "*.lsp") should signal FILE-ERROR.
h: (MAKE-CONCATENATED-STREAM (MAKE-STRING-OUTPUT-STREAM))
should signal TYPE-ERROR.
i: MAKE-TWO-WAY-STREAM doesn't check that its arguments can
crashes SBCL. In general tracing anything which is used in the
implementation of TRACE is likely to have the same problem.

- As reported by Daniel Solaz on cmucl-help@cons.org 2000-11-23,
- SXHASH returns the same value for all non-STRUCTURE-OBJECT instances,
- notably including all PCL instances. There's a limit to how much
- SXHASH can do to return unique values for instances, but at least
- it should probably look at the class name, the way that it does
- for STRUCTURE-OBJECTs.

The compiler doesn't like &OPTIONAL arguments in LABELS and FLET
(SB-C::LAMBDA-TAIL-SET

- (DECLAIM (OPTIMIZE ..)) doesn't work. E.g. even after
- (DECLAIM (OPTIMIZE (SPEED 3))), things are still optimized with
- the previous SPEED policy. This bug will probably get fixed in
- 0.6.9.x in a general cleanup of optimization policy.

(DECLAIM (OPTIMIZE ..)) doesn't work properly inside LOCALLY forms.
Evidently Python thinks of the lambda as a code transformation so
much that it forgets that it's also an object.

The DEFSTRUCT section of the ANSI spec, in the :CONC-NAME section,

still some functions named "hairy arg processor" and
"SB-INT:&MORE processor".

- SUBTYPEP does not work well with redefined classes:
- ---
- * (defclass a () ())
- #<STANDARD-CLASS A>
- * (defclass b () ())
- #<STANDARD-CLASS B>
- * (subtypep 'b 'a)
- NIL
- T
- * (defclass b (a) ())
- #<STANDARD-CLASS B>
- * (subtypep 'b 'a)
- T
- T
- * (defclass b () ())
- #<STANDARD-CLASS B>
-
- ;;; And now...
- * (subtypep 'b 'a)
- T
- T
-
- This is probably due to underzealous clearing of the type caches; a
- brute-force solution in that case would be to make a defclass expand
- into something that included a call to SB-KERNEL::CLEAR-TYPE-CACHES,
- but there may be a better solution.

When a function is called with too few arguments, causing the

- The type system still can't quite deal with all useful identities;

Array types with element-types of some unknown type are falsely being

Since this is a reasonable user error, it shouldn't be reported as

+ sbcl's treatment of at least macro lambda lists is too permissive;
+ e.g., in sbcl-0.7.3.7:
+ (defmacro foo (&rest rest bar) `(,bar ,rest))

+ (WRITE-STRING (> X 0) "+" "0"))
+ compiled in a context where the compiler can prove that X is NIL,
+ and the compiler complains that (> X 0) causes a type error because

+ COMPILE and COMPILE-FILE returned FAILURE-P=T for perfectly legal
