Ideally, uninterning a symbol would allow it, and its associated
FDEFINITION and PROCLAIM data, to be reclaimed by the GC. However,
macro is unhappy with the illegal syntax in the method body, and
is giving an unclear error message.

- (reported by Dan Barlow on sbcl-devel 2002-05-10)
- In sbcl-0.7.3.12, doing
- (defstruct foo bar baz)
- (compile nil (lambda (x) (or x (foo-baz x))))
- gives an error
- debugger invoked on condition of type SB-INT:BUG:
- full call to SB-KERNEL:%INSTANCE-REF
- This is probably a bug in SBCL itself. [...]
- Since this is a reasonable user error, it shouldn't be reported as
- an SBCL bug.

172:
sbcl's treatment of at least macro lambda lists is too permissive;
e.g., in sbcl-0.7.3.7:
(defun bug178alternative (x)
(funcall (the nil x)))

- Compiling
- (in-package :cl-user)
- (defun bar (x)
- (declare (type 0 x))

- bad thing to be a type specifier: 0
- which seems fine, but also enters the debugger (instead of having
- the compiler handle the error, convert it into a COMPILER-ERROR, and
- continue compiling) which seems wrong.

Even where floating point handling is being dealt with relatively
well (as of sbcl-0.7.5, on sparc/sunos and alpha; see bug #146), the
APD further reports that this bug is not present in CMUCL.
