+ Probably SBCL should stop accepting the "~:8D"-style format arguments,
+ or at least issue a warning.

+ (probably related to bug #65)
+ The compiler doesn't like &OPTIONAL arguments in LABELS and FLET
+ forms. E.g.
+ (DEFUN FIND-BEFORE (ITEM SEQUENCE &KEY (TEST #'EQL))
+ (LABELS ((FIND-ITEM (OBJ SEQ TEST &OPTIONAL (VAL NIL))
+ (LET ((ITEM (FIRST SEQ)))
+ (COND ((NULL SEQ)
+ (VALUES NIL NIL))
+ ((FUNCALL TEST OBJ ITEM)
+ (VALUES VAL SEQ))
+ (T
+ (FIND-ITEM OBJ (REST SEQ) TEST (NCONC VAL `(,ITEM))))))))
+ (FIND-ITEM ITEM SEQUENCE TEST)))
+ from David Young's bug report on cmucl-help@cons.org 30 Nov 2000
+ causes sbcl-0.6.9 to fail with
+ error in function SB-KERNEL:ASSERT-ERROR:
+ The assertion (EQ (SB-C::LAMBDA-TAIL-SET SB-C::CALLER)
+ (SB-C::LAMBDA-TAIL-SET
+ (SB-C::LAMBDA-HOME SB-C::CALLEE))) failed.
+

+ (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.
+
+72:
+ (DECLAIM (OPTIMIZE ..)) doesn't work properly inside LOCALLY forms.
+
+74:
+ As noted in the ANSI specification for COERCE, (COERCE 3 'COMPLEX)
+ gives a result which isn't COMPLEX. The result type optimizer
+ for COERCE doesn't know this, perhaps because it was written before
+ ANSI threw this curveball: the optimizer thinks that COERCE always
+ returns a result of the specified type. Thus while the interpreted
+ function
+ (DEFUN TRICKY (X) (TYPEP (COERCE X 'COMPLEX) 'COMPLEX))
+ returns the correct result,
+ (TRICKY 3) => NIL
+ the compiled function
+ (COMPILE 'TRICKY)
+ does not:
+ (TRICKY 3) => T
+
+75:
+ As reported by Martin Atzmueller on sbcl-devel 26 Dec 2000,
+ ANSI says that WITH-OUTPUT-TO-STRING should have a keyword
+ :ELEMENT-TYPE, but in sbcl-0.6.9 this is not defined for
+ WITH-OUTPUT-TO-STRING.
+
+78:
+ ANSI says in one place that type declarations can be abbreviated even
+ when the type name is not a symbol, e.g.
+ (DECLAIM ((VECTOR T) *FOOVECTOR*))
+ SBCL doesn't support this. But ANSI says in another place that this
+ isn't allowed. So it's not clear this is a bug after all. (See the
+ e-mail on cmucl-help@cons.org on 2001-01-16 and 2001-01-17 from WHN
+ and Pierre Mai.)
+
+79:
+ as pointed out by Dan Barlow on sbcl-devel 2000-07-02:
+ The PICK-TEMPORARY-FILE-NAME utility used by LOAD-FOREIGN uses
+ an easily guessable temporary filename in a way which might open
+ applications using LOAD-FOREIGN to hijacking by malicious users
+ on the same machine. Incantations for doing this safely are
+ floating around the net in various "how to write secure programs
+ despite Unix" documents, and it would be good to (1) fix this in
+ LOAD-FOREIGN, and (2) hunt for any other code which uses temporary
+ files and make it share the same new safe logic.
+
+80:
+ The subtle CMU CL bug discussed by Douglas Thomas Crosher on
+ cmucl-imp@cons.org 29 Jan 2001 sounds like something that probably
+ still exists in the corresponding SBCL code.
