+ SB-EXT:RUN-PROGRAM is currently non-functional on Linux/PPC;
+ attempting to use it leads to segmentation violations. This is
+ probably because of a bogus implementation of
+ os_restore_fp_control().
+
+266:
+ David Lichteblau provided (sbcl-devel 2003-06-01) a patch to fix
+ behaviour of streams with element-type (SIGNED-BYTE 8). The patch
+ looks reasonable, if not obviously correct; however, it caused the
+ PPC/Linux port to segfault during warm-init while loading
+ src/pcl/std-class.fasl. A workaround patch was made, but it would
+ be nice to understand why the first patch caused problems, and to
+ fix the cause if possible.
+
+268: "wrong free declaration scope"
+ The following code must signal type error:
+
+ (locally (declare (optimize (safety 3)))
+ (flet ((foo (x &optional (y (car x)))
+ (declare (optimize (safety 0)))
+ (list x y)))
+ (funcall (eval #'foo) 1)))
+
+269:
+ SCALE-FLOAT should accept any integer for its second argument.
+
+270:
+ In the following function constraint propagator optimizes nothing:
+
+ (defun foo (x)
+ (declare (integer x))
+ (declare (optimize speed))
+ (typecase x
+ (fixnum "hala")
+ (fixnum "buba")
+ (bignum "hip")
+ (t "zuz")))
+
+272:
+ All forms of GC hooks (including notifiers and finalisers) are currently
+ (since 0.8.0) broken for gencgc (i.e. x86) users
+
+273:
+ Compilation of the following two forms causes "X is unbound" error:
+
+ (symbol-macrolet ((x pi))
+ (macrolet ((foo (y) (+ x y)))
+ (declaim (inline bar))
+ (defun bar (z)
+ (* z (foo 4)))))
+ (defun quux (z)
+ (bar z))

+ CLHS says that type declaration of a symbol macro should not affect
+ its expansion, but in SBCL it does.

+ The following code (taken from CLOCC) takes a lot of time to compile:
