+Subject: [PATCH] Fix type error in fixed-mem-cache for SBCL 2.6.0
+
+In cl-ana.makeres, the fixed-mem-cache function uses
+(setf (cdr (last cache)) (list id)) where cache can be nil (initial
+state or after popping all elements). (last nil) returns nil, making
+(setf (cdr nil) ...) undefined. SBCL 2.6.0's stricter type inference
+catches this as a type conflict, causing COMPILE-FILE-ERROR.
+
+Replace with nconc which handles the nil case correctly.
