+  Compiling

+      (declare (ignorable b))
+      (ash (imagpart b) 57))
+  on PPC (and other platforms, presumably) gives an error during the
+  emission of FASH-ASH-LEFT/FIXNUM=>FIXNUM as the assembler attempts to
+  stuff a too-large constant into the immediate field of a PPC
+  instruction.  Either the VOP should be fixed or the compiler should be
+  taught how to transform this case away, paying particular attention
+  to side-effects that might occur in the arguments to ASH.

+384: Compiler runaway on very large character types
+
+  (compile nil '(lambda (x)
+                    (declare (type (member #\a 1) x))
+                    (the (member 1 nil) x)))
+
+  The types apparently normalize into a very large type, and the compiler
+  gets lost in REMOVE-DUPLICATES.  Perhaps the latter should use
+  a better algorithm (one based on hash tables, say) on very long lists
+  when :TEST has its default value?
+
+  A simpler example:
+
+  (compile nil '(lambda (x) (the (not (eql #\a)) x)))
+
+  (partially fixed in 0.9.3.1, but a better representation for these
+   types is needed.)
