+  (BUU 1) returns garbage.
+
+  The problem is that both EVALs sequentially write to the same LVAR.

+  (Reported by Dave Roberts.)
+  Local INLINE/NOTINLINE declaration removes local FTYPE declaration:
+
+    (defun quux (x)
+      (declare (ftype (function () (integer 0 10)) fee)
+               (inline fee))
+      (1+ (fee)))
+
+  uses generic arithmetic with INLINE and fixnum without.
